64K x 36 Bit Pipelined BurstRAM Synchronous Fast Static RAM

The MCM63P636 is a 2M–bit synchronous fast static RAM designed to provide burstable, high performance, secondary cache for advanced microprocessors. It is organized as 64K words of 36 bits each. This device integrates input registers, an output register, a 2–bit address counter, and a high speed SRAM onto a single monolithic circuit for reduced parts count in cache data RAM applications. Synchronous design allows for precise cycle control with the use of an external clock (K) and external strobe clock (SK).

The MCM63P636 operates from a 3.3 V core power supply, a 2.0 V input power supply, and a 2.0 V I/O power supply. These power supplies are designed so that power sequencing is not required.
