4M Late Write 2.
5 V I/O
The MCM69R738A/820A is a 4 megabit synchronous late write fast static RAM designed to provide high performance in secondary cache and ATM switch, Telecom, and other high speed memory applications.
The MCM69R820A organized as 256K words by 18 bits, and the MCM69R738A organized as 128K words by 36 bits wide are fabricated in Motorola’s high performance silicon gate Bi
CMOS technology.
The differential CK clock inputs control the timing of read/write operations of the RAM.
At the rising edge of the CK clock all addresses, write enables, and synchronous selects are registered.
An internal buffer and special logic en...
