128K x 36 and 256K x 18 Bit Pipelined BurstRAM Synchronous Fast Static RAM

The MCM63P737K and MCM63P819K are 4M–bit synchronous fast static RAMs designed to provide a burstable, high performance, secondary cache. The MCM63P737K (organized as 128K words by 36 bits) and the MCM63P819K (organized as 256K words by 18 bits) integrate input registers, an output register, a 2–bit address counter, and high speed SRAM onto a single monolithic circuit for reduced parts count in cache data RAM applications. Synchronous design allows precise cycle control with the use of an external clock (K).

The MCM63P737K and MCM63P819K operate from a 3.3 V core power supply and all outputs operate on a 2.5 V or 3.3 V power supply. All inputs and outputs are JEDEC standard JESD8–5 compatible.
