CMOS IC

LC35W256EM, ET-10W

256K (32K words

8 bits) SRAM

Control pins: OE and CE

Overview

The LC35W256EM-10W and LC35W256ET-10W are

asynchronous silicon-gate CMOS SRAMs with a 32768-

word by 8-bit structure. These are full-CMOS devices

with 6 transistors per memory cell, and feature ultralow-

voltage operation, a low operating current drain, and an

ultralow standby current. Control inputs include OE for

fast memory access and CE for power saving and device

selection. This makes these devices optimal for systems

that require low power or battery backup, and makes

memory expansion easy. The ultralow standby current

allows these devices to be used with capacitor backup as

well.
