CMOS STATIC RAM
Description
The TC55B4257J is a 1,048,576 bit high speed Bi
CMOS static random access memory organized as 262,144 words by 4 bits and operated from a single 5V supply. Toshiba's Bi
CMOS technology and advanced circuit design enable high speed operation.
The TC55B4257J features low power dissipation when the device is deselected using chip enable (CE), and has an output enable input (OE) for fast memory access.
The TC55B4257J is suitable for use in applications where high speed is required such as cache memory, high speed storage, and main memory. All inputs and outputs are TIL compatible.
The TC55B4257J is available in a 400mil width, 32-pin SOJ suitable for high density surface assembly.
