71T75802数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The 71T75802 2.5V CMOS Synchronous SRAM organized as 1M x 18 (18 Megabit). 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 71T75802 contains data I/O, address and control signal registers.
