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.

• 3.3 V LVTTL and LVCMOS Compatible
