Advance Information

128K x 32 Bit Pipelined

BurstRAM Synchronous

Fast Static RAM

The MCM63P733A is a 4M–bit synchronous fast static RAM designed to pro-

vide a burstable, high performance, secondary cache for the PowerPC and

other high performance microprocessors. It is organized as 128K words of 32

bits each, fabricated with high performance silicon gate CMOS technology.

This device integrates 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 pre-

cise cycle control with the use of an external clock (K). CMOS circuitry reduces

the overall power consumption of the integrated functions for greater reliability.

Addresses (SA), data inputs (DQx), and all control signals except output

enable (G) and Linear Burst Order (LBO) are clock (K) controlled through

positive–edge–triggered noninverting registers.

CASE 983A–01

Bursts can be initiated with either ADSP or ADSC input pins. Subsequent burst

addresses can be generated internally by the MCM63P733A (burst sequence

operates in linear or interleaved mode dependent upon state of LBO) and con-

trolled by the burst address advance (ADV) input pin.

Write cycles are internally self–timed and are initiated by the rising edge of the

clock (K) input. This feature eliminates complex off–chip write pulse generation

and provides increased timing flexibility for incoming signals.

Synchronous byte write (SBx), synchronous global write (SGW), and synchro-

nous write enable (SW) are provided to allow writes to either individual bytes or

to all bytes. The four bytes are designated as “a”, “b”, “c”, and “d”. SBa controls

DQa, SBb controls DQb, etc. Individual bytes are written if the selected byte

writes SBx are asserted with SW. All bytes are written if either SGW is asserted

or if all SBx and SW are asserted.

For read cycles, pipelined SRAMs output data is temporarily stored by an

edge–triggeredoutput register and then released to the output buffers at the next

rising edge of clock (K).

The MCM63P733A operates 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.
