128K x 32 Bit Flow–Through
BurstRAM Synchronous
Fast Static RAM
vide a burstable, high performance, secondary cache for the PowerPC
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, 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). CMOS circuitry reduces the overall power con-
sumption of the integrated functions for greater reliability.
enable (G) and Linear Burst Order (LBO) are clock (K) controlled through
positive–edge–triggered noninverting registers.
addresses can be generated internally by the MCM63F733A (burst sequence
operates in linear or interleaved mode dependent upon state of LBO) and con-
trolled by the burst address advance (ADV) input pin.
clock (K) input. This feature eliminates complex off–chip write pulse generation
and provides increased timing flexibility for incoming signals.
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.
