NEe Microcomputers, Inc. 4096 x 1 BIT STATIC RAMI NEe J.L PD2147-2 p.PD2147-3 J.L PD2147-5 FEATURES The IlPD2147 is a 4096-bit static Random Access Memory organized as 4096 words by 1-bit. Using a scaled NMOS technology, it incorporates an innovative design approach which provides the ease-of-use features associated with non-clocked static memories and the reduced standby power dissipation associated with clocked static memories. The result is low standby power dissipation without the need for clocks, address setup and hold times. In addition, data rates are not reduced due to cycle times that are longer than access times. CS controls the power down feature. In less than a cycle time after CS goes high deselecting the IlPD2147 - the part automatically reduces its power requireme"ts and remains in this lower power standby mode as long as CS remains high. This del/ice feature results in system power savings as great as 85"10 in larger systems, where the majority of devices are deselec...
