Multi-Chip Package MEMORY 512M Bit(64Mx8) Nand Flash*2 / 256M Bit (2Mx32x4Banks) Mobile SDRAM*2 The KBE00F005A is a Multi Chip Package Memory which combines 1Gbit Nand Flash Memory(organized with two pieces of 512Mbit Nand Flash Memory) and 512Mbit synchronous high data rate Dynamic RAM.(organized with two pieces of 256Mbit Mobile SDRAM) 1Gbit NAND Flash memory is organized as 128M x8 bits and 512Mbit Mobile SDRAM is organized as 4M x32 bits x4 banks In 1Gbit NAND Flash,its NAND cell provides the most cost-effective solution for the solid state mass storage market. A program oper- ation can be performed in typically 200µs on the 528-byte page and an erase operation can be performed in typically 2ms on a 16K- byte block. Data in the data register can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command inputs. The on-chip write controller automates all program and erase functions including pulse rep- etition, where required, and internal verify and margining of data. Even the write-intensive systems can take advantage of the extended reliability of 100K program/erase cycles by providing E CC(Error Correcting Code) with real time mapping-out algorithm. This device is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable appli- cations requiring non-volatility. In 512Mbit SDRAM, Synchronous design make a device controlled precisely with the use of system clock and I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. The KBE00F005A is suitable for use in data memory of mobile communication system to reduce not only mount area but also power consumption. This device is available in 137-ball FBGA Type.

KBE00F005A-D411 MCP MEMORY June 2005 8 Revision 1.0 PIN DESCRIPTION NOTE : Connect all VCC and VSS pins of each device to common power supply outputs. Do not leave VCC or VSS disconnected. Pin Name Pin Function I/O0 ~ I/O7 DATA INPUTS/OUTPUTS The I/O pins are used to input command, address and data, and to output data during read operations. The I/ O pins float to high-z when the chip is deselected or when the outputs are disabled. CLE COMMAND LATCH ENABLE The CLE input controls the activating path for commands sent to the command register. When active high, commands are latched into the command register through the I/O ports on the rising edge of the WE signal. ALE ADDRESS LATCH ENABLE The ALE input controls the activating path for address to the internal address registers. Addresses are latched on the rising edge of WE with ALE high. CE CHIP ENABLE The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and the device does not return to standby mode in program or erase operation. Regarding CE control during read operation, refer to ’Page read’ section of Device operation . RE READ ENABLE The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the falling edge of RE which also increments the internal column address counter by one. WE WRITE ENABLE The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE pulse. WP WRITE PROTECT The WP pin provides inadvertent write/erase protection during power transitions. The internal high voltage generator is reset when the WP pin is active low. R/B READY/BUSY OUTPUT The R/B output indicates the status of the device operation. When low, it indicates that a program, erase or random read operation is in process and returns to high state upon completion. It is an open drain output and does not float to high-z condition when the chip is deselected or when outputs are disabled. VccQ OUTPUT BUFFER POWER VccQ is the power supply for Output Buffer. VccQ is internally connected to Vcc, thus should be biased to Vcc. Vcc POWER VCC is the power supply for device. Vss GROUND N.C NO CONNECTION Lead is not internally connected. DNU DO NOT USE Leave it disconnected.

Program Error Yes No Yes Error in write or read operation Within its life time, additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the b lock failure rate.The following possible failure modes should be consid ered to implement a highly reliable system. In the case of st atus read failure after erase or program, block replacement should be done. Because program status fail during a page program does not affect the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased empty block and reprogramming the current tar get data and copying the rest of the replac ed block. In case of Read, ECC must be employed. To improve the efficiency of memory space, it is re commended that the read failure due to single bit error should be reclaimed by ECC without any block replacement. The block failur e ratein the qualification report does not include those recla imed blocks.

Once the command is latched, it does not need to be written for the following page read o pera- tion. Three types of operations are available : random read, serial page read and sequential row read. The random read mode is enabled when the page address is change d. The 528 bytes of data within the selected page are trans- ferred to the data registers in less than 15µs(t R). The system controller can detect the completion of this data transfer(tR) by analyz- ing the output of R/B pin. Once the data in a page is loaded into the registers, they may be read out in 50ns cycle time by sequentially pulsing RE. High to low transitions of the RE clock output the data stating from the selected column address up to the last column address. The way the Read1 and Read2 commands work is like a pointer set to either the main area or the spare area. The spare area of bytes 512 to 527 may be selectively accessed by writing the Read2 command. Addresses A 0 to A3 set the starting address of the spare area while addresses A4 to A7 are ignored. Unless the operation is aborted, the page address is automatically incremented for sequential row read as in Read1 operation and spare sixteen bytes of each page may be sequentially read. The Read1 com- mand(00h/01h) is needed to move the pointer back to the main area. Figures 9 to 12 show typical sequence and timings for each read operation.

KBE00F005A-D411 MCP MEMORY June 2005 READ STATUS The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE does not need to be toggled for updated status. Refer to table 4 for specific Status Register definitions. The command register remains in Status Read mode until further commands are issued to i t. Therefore, if the status regi ster is read during a random read cycle, a read command(00h or 50h) should be given before sequential page read cycle. For Read Status of Multi Plane Program/Erase, the Read Multi- Plane Status command(71h) should be used to find out whether multi-plane program or erase operation is completed, and whether the program or erase operation is completed successfully. The pass/fail status data must be checked only in the Ready condition after the completion of Multi-Plane program or erase operation. Table4. Read Staus Register Definition NOTE : 1. I/O 0 describes combined Pass/Fail condition for all planes. If any of the selected multiple pages/blocks fails in Program/ Erase operation, it sets "Fail" flag. 2.

KBE00F005A-D411 MCP MEMORY June 2005 D. DEVICE OPERATIONS BANK ADDRESSES (BA0 ~ BA1) This SDRAM is organized as two chips which has four indepen- dent banks of 2,097,152 words x 32 bits memory arrays. The BA0 ~ BA1 inputs are latched at the time of assertion of RAS and CAS to select the bank to be used for the operation. The bank addresses BA0 ~ BA1 are latched at bank active, read, write, mode register set and precharge operations. ADDRESS INPUTS (A0 ~ A12) The 21 address bits are required to decode the 8,388,608 word locations are multiplexed into 13 address input pins (A0 ~ A12). The 13 bit row addresses are latched along with RAS and BA0 ~ BA1 during bank activate command. The 8 bit column addresses (A0 ~ A7) are latched along with CAS , WE and BA0 ~ BA1 during read or write command. ADDRESSES of 512Mb CLOCK (CLK) The clock input is used as the reference for all SDRAM opera- tions. All operations are synchronized to the positive going edge of the clock. The clock transitions must be monotonic between V IL and V IH. During operation with CKE high all inputs are assumed to be in a valid state (low or high) for the duration of set-up and hold time around positive edge of the clock in order to function well Q perform and ICC specifications. CLOCK ENABLE (CKE) The clock enable(CKE) gates the clock onto SDRAM. If CKE goes low synchronously with clock (set-up and hold time are the same as other inputs), the internal clock is suspended from the next clock cycle and the state of output and burst address is fro- zen as long as the CKE remains low. All other inputs are ignored from the next clock cycle after CKE goes low. When all banks are in the idle state and CKE goes low synchronously with clock, the SDRAM enters the power down mode from the next clock cycle. The SDRAM remains in the power down mode ignoring the other inputs as long as CKE remains low. The power down exit is syn- chronous as the internal clock is suspended. When CKE goes high at least "1CLK + tSS" before the high going edge of the clock, then the SDRAM becomes active from the same clock edge accepting all the input commands. NOP and DEVICE DESELECT When RAS , CAS and WE are high, the SDRAM performs no operation (NOP). NOP does not initiate any new operation, but is needed to complete operations which require more than single clock cycle like bank activate, burst read, auto refresh, etc. The device deselect is also a NOP and is entered by asserting CS high. CS high disables the command decoder so that RAS, CAS, WE and all the address inputs are ignored.

KBE00F005A-D411 MCP MEMORY June 2005 D. DEVICE OPERATIONS (continued) DQM OPERATION The DQM is used to mask input and output operations. It works similar to OE during read operation and inhibits writing during write operation. The read late ncy is two cycles from DQM and zero cycle for write, which means DQM masking occurs two cycles later in read cycle and occurs in the same cycle during write cycle. DQM operation is synchronous with the clock. The DQM signal is important during bu rst interruptions of write with read or precharge in the SDRAM. Due to asynchronous nature of the internal write, the DQM operation is critical to avoid unwanted or incomplete writes when the complete burst write is not required. Please refer to DQM timing diagram also. MODE REGISTER SET (MRS) The mode register stores the data for controlling the various operating modes of SDRAM. It programs the CAS latency, burst type, burst length, test mode and various vendor specific options to make SDRAM useful for variety of different applications. The default value of the mode register is not defined, therefore the mode register must be written after power up to operate the SDRAM. The mode register is written by asserting low on CS RAS, CAS and WE (The SDRAM should be in active mode with CKE already high prior to writing the mode register). The state of address pins A0 ~ An and BA0 ~ BA1 in the same cycle as CS , RAS, CAS and WE going low is the data written in the mode reg- ister. Two clock cycles is required to complete the write in the mode register. The mode register contents can be changed using the same command and clock cycle requirements during opera- tion as long as all banks are in the idle state. The mode register is divided into various fields depending on the fields of functions. The burst length field uses A0 ~ A2, burst type uses A3, CAS latency (read latency from column address) use A4 ~ A6, vendor specific options or test mode use A7 ~ A8, A10/AP ~ An and BA0 ~ BA1. The write burst length is programmed using A9. A7 ~ A8, A10/AP ~ An and BA0 ~ BA1 must be set to low for normal SDRAM operation. Refer to the table for specific codes for vari- ous burst length, burst type and CAS latencies. EXTENDED MODE REGISTER SET (EMRS) The extended mode register stores the data for selecting driver strength, partial self refresh or temperature compensated self refresh. EMRS cycle is not mandatory and the EMRS command needs to be issued only when DS or PASR is used. The default state without EMRS command issued is half driver strength, and all 4 banks refreshed. The extended mode register is written by asserting low on CS , RAS, CAS, WE and high on BA1 ,low on BA0(The SDRAM should be in all bank precharge with CKE already high prior to writing into the extended mode register). The state of address pins A0 ~ A12 in the same cycle as CS RAS, CAS and WE going low is written in the extended mode register. Two clock cycles are required to complete the write operation in the extended mode register. The mode register con- tents can be changed using the same command and clock cycle requirements during operation as long as all banks are in the idle state. A0 - A2 are used for partial self refresh , A5 - A6 are used for Driver strength, "Low" on BA1 and "High" on BA0 are used for EMRS. All the other address pins except A0-A2, A5-A6 and BA1, BA0 must be set to low for proper EMRS operation. Refer to the table for specific codes. BANK ACTIVATE. The bank activate command is used to select a random row in an idle bank. By asserting low on RAS and CS with desired row and bank address, a row access is init iated. The read or write opera- tion can occur after a time delay of t RCD(min) from the time of bank activation. tRCD is an internal timing parameter of SDRAM, therefore it is dependent on operating clock frequency. The mini- mum number of clock cycles required between bank activate and read or write command should be calculated by dividing t RCD(min) with cycle time of the clock and then rounding off the result to the next higher integer.

KBE00F005A-D411 MCP MEMORY June 2005 D. DEVICE OPERATIONS (continued) The SDRAM has four internal banks in the same chip and shares part of the internal circuitry to reduce chip area, therefore it restricts the activation of four banks simultaneously. Also the noise generated during sensing of each bank of SDRAM is high, requiring some time for power supplies to recover before another bank can be sensed reliably. t RRD(min) specifies the minimum time required between activating different bank. The number of clock cycles required between different bank activation must be calculated similar to t RCD specification. The minimum time required for the bank to be active to initiate sensing and restoring the complete row of dynamic cells is determined by t RAS(min). Every SDRAM bank activate command must satisfy t RAS(min) specification before a prechar ge command to that active bank can be asserted. The maximum time any bank can be in the active state is determined by t RAS(max). The number of cycles for both tRAS(min) and t RAS(max) can be calculated similar to t RCD specification. BURST READ The burst read command is used to access burst of data on con- secutive clock cycles from an active row in an active bank. The burst read command is issued by asserting low on CS and CAS with WE being high on the positive edge of the clock. The bank must be active for at least t RCD(min) before the burst read com- mand is issued. The first output appears in CAS latency number of clock cycles after the issue of burst read command. The burst length, burst sequence and latency from the burst read command is determined by the mode register which is already pro- grammed. The burst read can be initiated on any column address of the active row. The address wraps around if the initial address does not start from a boundary such that number of outputs from each I/O are equal to the burst length programmed in the mode register. The output goes into high-impedance at the end of the burst, unless a new burst read was initiated to keep the data out- put gapless. The burst read can be terminated by issuing another burst read or burst write in th e same bank or the other active bank or a precharge command to the same bank. The burst stop command is valid at every page burst length. BURST WRITE The burst write command is similar to burst read command and is used to write data into the SDRAM on consecutive clock cycles in adjacent addresses depending on burst length and burst sequence. By asserting low on CS , CAS and WE with valid col- umn address, a write burst is init iated. The data inputs are pro- vided for the initial address in the same clock cycle as the burst write command. The input buffer is deselected at the end of the burst length, even though the internal writing can be completed yet. The writing can be completed by issuing a burst read and DQM for blocking data inputs or burst write in the same or another active bank. The burst stop command is valid at every burst length. The write burst can also be terminated by using DQM for blocking data and procreating the bank t RDL after the last data input to be written into the active row. See DQM OPER- ATION also. ALL BANKS PRECHARGE All banks can be precharged at the same time by using Pre- charge all command. Asserting low on CS , RAS, and WE with high on A10/AP after all banks have satisfied t RAS(min) require- ment, performs precharge on all banks. At the end of t RP after performing precharge to all the banks, all banks are in idle state. PRECHARGE The precharge operation is performed on an active bank by asserting low on CS , RAS, WE and A10/AP with valid BA0 ~ BA1 of the bank to be precharged. The precharge command can be asserted anytime after t RAS(min) is satisfied from the bank active command in the desired bank. t RP is defined as the minimum number of clock cycles required to complete row precharge is calculated by dividing t RP with clock cycle time and rounding up to the next higher integer. Care should be taken to make sure that burst write is completed or DQM is used to inhibit writing before precharge command is asserted. The maximum time any bank can be active is specified by t RAS(max). Therefore, each bank activate command. At the end of precharge, the bank enters the idle state and is ready to be activated again. Entry to Power down, Auto refresh, Self refresh and Mode register set etc. is possible only when all banks are in idle state.

KBE00F005A-D411 MCP MEMORY June 2005 D. DEVICE OPERATIONS (continued) AUTO PRECHARGE The precharge operation can also be performed by using auto precharge. The SDRAM internally generates the timing to satisfy tRAS(min) and "t RP" for the programmed burst length and CAS latency. The auto precharge command is issued at the same time as burst read or burst write by asserting high on A10/AP. If burst read or burst write by asserting high on A10/AP, the bank is left active until a new command is asserted. Once auto precharge command is given, no new commands are possible to that partic- ular bank until the bank achieves idle state. AUTO REFRESH The storage cells of 64Mb, 128Mb and 256Mb SDRAM need to be refreshed every 64ms to maintain data. An auto refresh cycle accomplishes refresh of a single row of storage cells. The inter- nal counter increments automatically on every auto refresh cycle to refresh all the rows. An auto refresh command is issued by asserting low on CS , RAS and CAS with high on CKE and WE . The auto refresh command can only be asserted with all banks being in idle state and the device is not in power down mode (CKE is high in the previous cycle). The time required to com- plete the auto refresh operation is specified by t RC(min). The min- imum number of clock cycles required can be calculated by driving t RC with clock cycle time and them rounding up to the next higher integer. The auto refresh command must be followed by NOP's until the auto refresh operation is completed. All banks will be in the idle state at the end of auto refresh operation. The auto refresh is the preferred refresh mode when the SDRAM is being used for normal data transactions. The 64Mb and 128Mb SDRAM’s auto refresh cycle can be performed once in 15.6us or a burst of 4096 auto refresh cycles once in 64ms. The 256Mb and 512Mb SDRAM’s auto refresh cycle can be performed once in 7.8us or a burst of 8192 auto refresh cycles once in 64ms. SELF REFRESH The self refresh is another refresh mode available in the SDRAM. The self refresh is the preferred refresh mode for data retention and low power operation of SDRAM. In self refresh mode, the SDRAM disables the internal clock and all the input buffers except CKE. The refresh addressing and timing are inter- nally generated to reduce power consumption. The self refresh mode is entered from all banks idle state by asserting low on CS , RAS, CAS and CKE with high on WE. Once the self refresh mode is entered, only CKE state being low mat- ters, all the other inputs including the clock are ignored in order to remain in the self refresh mode. The self refresh is exited by restarting the external clock and then asserting high on CKE. This must be followed by NOP's for a minimum time of tSRFX before the SDRAM reaches idle state to begin normal operation. In case that the system uses burst auto refresh during normal operation, it is recommended to use burst 8192 auto refresh cycles for 256Mb and 512Mb, and burst 4096 auto refresh cycles for 128Mb and 64Mb immediately before entering self refresh mode and after exiting in self refresh mode. On the other hand, if the syst em uses the distributed auto refresh, the system only has to keep the refresh duty cycle.

KBE00F005A-D411 MCP MEMORY June 2005 tSS tSS Auto Refresh Command PRE tRP(min) tARFC(min) Auto CKE = High Refresh CMD An auto refresh command is issued by having CS , RAS and CAS held low with CKE and WE high at the rising edge of the clock(CLK). All banks must be precharged and idle for tRP(min) before the auto refresh command is applied. No control of the external address pins is required once this cycle has started because of the internal address counter. When the refresh cycle has completed, all banks will be in the idle state. A delay between the auto refresh command and the next activate command or subsequent auto refresh command must be greater than or equal to the tARFC(min). CLK A Self Refresh command is defined by having CS , RAS, CAS and CKE held low with WE high at the rising edge of the clock. Once the self Refresh command is initiated, CKE must be held low to keep the device in Self Refresh mode. After 1 clock cycle from the self refresh command, all of the external control signals including system clock(CLK) can be disabled except CKE. The clock is internally disabled during Self Refresh operation to reduce power. To exit the Self Refresh mode, supply stable clock input before returning CKE high, assert deselect or NOP command and then assert CKE high . In case that the system uses burst auto refresh during normal opreation, it is recommended to use burst 4096 auto refresh cycle immediately before entering self refresh mode and after exiti ng in self refresh mode. On the other hand, if the system uses t he distributed auto refresh, the syst em only has to keep the refresh duty cycle.
