Description

The LC3564B, LC3564BS, LC3564BM, and LC3564BT are 8192-word ´ 8-bit asynchronous silicon gate CMOS SRAMs. These are full CMOS type SRAMs that adopt a six-transistor memory cell and feature fast access times, low operating power dissipation, and an ultralow standby current. These SRAMs provide three control signal inputs: an OE input for high-speed memory access, and two chip enable lines, CE1 and CE2, for low power mode and device selection. These means that these SRAMs area ideal for systems that require low power and battery backup, and that they support easy memory expansion. The ultralow standby current that is a feature of these SRAMs allows them to be used with capacitor backup as well. Since these SRAMs support 3-V operation, they are also appropriate for use in portable battery operated systems.
