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 MCM63Z736 (organized
as 128K words by 36 bits) and the MCM63Z818 (organized as 256K words by
18 bits) are fabricated in Motorola’s 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 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, pipelined SRAM output data is temporarily stored by an edge–
triggered output register and then released to the output buffers at the next rising
edge of clock (CK).
