Asynchronous Silicon Gate CMOS LSI
LC36256ALL, AMLL-70/85/10/12
256 K (32768 words × 8 bits) SRAM
Overview
The LC36256ALL, AMLL are fully asynchronous silicon gate CMOS static RAMs with a 32768 words × 8 bits configuration. T h i s series has CE chip enable pin for device select/nonselect control and an OE output enable pin for output control, and features high speed as well as low power dissipation. Current dissipation is notably reduced during stand-by and data retention. For these reasons, this series is most suited f o r use in systems requiring high speed, low power c o n s u m p t i o n and long-term battery backup. Simple memory capacity expansion is also supported.
