OPTION TIMING MARKING 45ns -45 60ns -60 PACKAGE 42-pin SOJ J 44/50-pin TSOPII S GENERAL DESCRIPTION The T2316160A is a randomly accessed solid state memory containing 16,777,216 bits organized in a x16 configuration. The T2316160A has both BYTE WRITE and WORD WRITE access cycles via two CAS pins. It offers Fast Page mode with Extended Data Output. The T2316160A CAS function and timing are determined by the first CAS to transition low and by the last to transition back high. Use only one of the two CAS and leave the other staying high during WRITE will result in a BYTE WRITE. CASL to transition low in a WRITE cycle will write data into the lower byte (DQ0~DQ7), and CASH transiting low will write data into the upper byte (DQ8~DQ15).

Taiwan Memory Technology, Inc. reserves the right P. 6 Publication Date: APR. 2002 to change products or specifications without notice. Revision:A Notes: 1. An initial pause of 200us is required after power-up followed by eight RAS refresh cycles ( RAS only or CBR) before proper device operation is assured. The eight RAS cycle wake-ups should be repeated any time the tREF refresh requirement is exceeded. 2. V IH(2.4V) and VIL(0.8V) are reference levels for measuring timing of input signals. Transition times are measured between VIH(2.4V) and VIL(0.8V). 3. In addition to meet the transition rate specification, all input signals must transit between VIH and VIL in a monotonic manner. 4. Assume that t RCD < t RCD(max). If t RCD is greater than the maximum recommended value shown in this table, t RAC will increase by the amount that tRCD exceeds the value shown. 5. Assume that t RCD ≥ tRCD(max) . 6. Enables on-chip refresh and address counters. 7. Operation within the t RCD(max) limit ensures that t RAC(max) can be met. t RCD(max) is specified as a reference point only; if t RCD is greater than the specified t RCD(max) limit, access time is controlled by tCAC. 8. Operation within the t RAD limit ensures that tRAC(max) can be met. t RAD(max) is specified as a reference point only; if t RAD is greater than the specified t RAD(max) limit, access time is controlled by tAA. 9. Either t RCH or t RRH must be satisfied for a READ cycle. 10. tOFF1(max) defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL. 11. tWCS, t RWD, t AWD and t CWD are restrictive operating parameters in LATE WRITE and READ-MODIFY-WRITE cycles only. If t WCS ≥ tWCS(min), the cycle is an EARLY WRITE cycle and the data output will remain an open circuit throughout the entire cycle. If t RWD ≥ tRWD(min), t AWD ≥ tAWD(min) and t CWD ≥ tCWD(min), the cycle is READ-WRITE and the data output will contain data read from the selected cell. If neither of the above conditions is met, the state of I/O (at access time and until CAS and RAS or OE go back to VIH) is indeterminate. OE held high and WE taken low after CAS goes low result in a LATE WRITE ( OE - controlled) cycle. 12. These parameters are referenced to CAS leading edge in EARLY WRITE cycles and WE leading edge in LATE WRITE or READ- MODIFY-WRITE cycles. 13. During a READ cycle, if OE is low then taken HIGH before CAS goes high, I/O goes open, if OE is tied permanently low, a LATE WRITE or READ-MODIFY-WRITE operation is not possible. 14. WRITE command is defined as WE going low. 15. LATE WRITE and READ-MODIFY-WRITE cycles must have both t OFF2 and t OEH met ( OE high during WRITE cycle) in order to ensure that the output buffers will be open during the WRITE cycles. 16. The I/Os open during READ cycles once tOFF1 or tOFF2 occur.
