The MCM69L737A/819A 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 MCM69L819A organized as 256K words by 18 bits, and the MCM69L737A organized as 128K words by 36 bits wide are fabricated in Motorola’s high performance silicon gate BiCMOS technology.

The RAM uses LVTTL 3.3 V inputs and outputs.

The synchronous write and byte enables allow writing to individual bytes or the entire word.
