Document # SRAM124 REV A Revised October 2005 P4C1024 HIGH SPEED 128K x 8 DUAL CHIP ENABLE CMOS STATIC RAM The P4C1024 device provides asynchronous opera- tions with matching access and cycle times. Memory locations are specified on address pins A 0 to A 16. Reading is accomplished by device selection (CE1 low and CE2 high) and output enabling ( OE) while write enable (WE) remains HIGH. By presenting the ad- dress under these conditions, the data in the ad- dressed memory location is presented on the data input/output pins. The input/output pins stay in the HIGH Z state when either CE 1 or OE is HIGH or WE or CE2 is LOW. The P4C1024 is a 1,048,576-bit high-speed CMOS static RAM organized as 128Kx8. The CMOS memory requires no clocks or refreshing, and has equal access and cycle times. Inputs are fully TTL-compatible. The RAM operates from a single 5V±10% tolerance power supply. Access times of 15 nanoseconds permit greatly en- hanced system operating speeds. CMOS is utilized to reduce power consumption to a low level. The P4C1024 is a member of a family of PACE RAM™ products offer- ing fast access times.
