Description The IDT71V65603/5803 are 3.3V high-speed 9,437,184-bit (9 Megabit) synchronous SRAMS. They are designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, they have been given the name ZBTTM, or Zero Bus Turnaround. Address and control signals are applied to the SRAM during one clock cycle, and two cycles later the associated data cycle occurs, be it read or write. The IDT71V65603/5803 contain data I/O, address and control signal registers. Output enable is the only asynchronous ...
