The 71V2556 3.3V CMOS Synchronous SRAM is organized as 128K x 36. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, it has been given the name ZBTTM , or Zero Bus Turnaround. The 71V2556 contains data I/O, address and control signal registers. It can provide four cycles of data for a single address presented to the SRAM .
