ricated using ISSI'sꢀhigh-performanceꢀCMOSꢀtechnol-
ogy.ꢀThisꢀhighlyꢀreliableꢀprocessꢀcoupledꢀwithꢀinnovativeꢀ
circuit design techniques, yields higher performance
and low power consumption devices.
•ꢀ High-performance,ꢀlow-powerꢀCMOSꢀprocess
•ꢀ Multipleꢀcenterꢀpowerꢀandꢀgroundꢀpinsꢀforꢀ
greater noise immunity
•ꢀ EasyꢀmemoryꢀexpansionꢀwithꢀCE and OE op-
tions
•ꢀ CE power-down
When CE is HIGH (deselected), the device assumes
a standby mode at which the power dissipation can be
reducedꢀdownꢀwithꢀCMOSꢀinputꢀlevels.
•ꢀ Fullyꢀstaticꢀoperation:ꢀnoꢀclockꢀorꢀrefreshꢀ

•ꢀ TTLꢀcompatibleꢀinputsꢀandꢀoutputs
•ꢀ Singleꢀpowerꢀsupply
TheꢀIS61WV20488ALL/BLLꢀandꢀIS64WV20488BLLꢀ
operate from a single power supply and all inputs are
TTL-compatible.ꢀ
