Product Proposal

256K x 36 and 512K x 18

Bit Pipelined ZBT RAM

Synchronous Fast Static RAM

The ZBT RAM is an 8M–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 MCM63Z836 (organized as

256K words by 36 bits) and the MCM63Z918 (organized as 512K words by 18

bits) are fabricated in Motorola’s high performance silicon gate CMOS tech-

nology. 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 positive–edge–triggered 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), sleep mode (ZZ), 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.

triggered output register and then released to the output buffers at the next rising

edge of clock (CK).
