Flow–Through ZBT™ RAM
Synchronous Fast Static RAM
The ZBT RAM is a 4M–bit synchronous fast static RAM designed to provide
zero bus turnaround. The ZBT RAM allows 100% use of bus cycles during
back–to–back read/write and write/read cycles. The MCM63Z737 is organized
as 128K words of 36 bits each and the MCM63Z819 is organized as 256K words
of 18 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 communication
applications. Synchronous design allows precise cycle control with the use of an
external clock (CK). CMOS circuitry reduces the overall power consumption of
the integrated functions for greater reliability.
Addresses (SA), data inputs (DQ), and all control signals except output enable
(G) and linear burst order (LBO) are clock (CK) controlled through positive–
edge–triggered noninverting registers.
Write cycles are internally self–timed and are initiated by the rising edge of the
clock (CK) input. This feature eliminates complex off–chip write pulse generation
and provides increased timing flexibility for incoming signals.
For read cycles, a flow–through SRAM allows output data to simply flow freely
from the memory array.
