4M Late Write 2.5 V I/O
The MCM69R738C/820C is a 4M–bit 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 MCM69R820C (organized as 256K words by 18 bits) and the MCM69R738C (organized as 128K words by 36 bits) are fabricated in Motorola’s high performance silicon gate BiCMOS technology.
The differential clock (CK) inputs control the timing of read/write operations of the RAM. At the rising edge of CK, all addresses, write enables, and synchronous selects are registered. An internal buffer and special logic enable the memory to accept write data on the rising edge of CK, a cycle after address and control signals. Read data is also driven on the rising edge of CK.
The RAM uses 2.5 V inputs and outputs.
The synchronous write and byte enables allow writing to individual bytes or the entire word.
