70V7599数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The 70V7599 is a high-speed 128K x 36 (4Mbit) synchronous Bank-Switchable Dual-Ported SRAM is organized into 64 independent 2Kx36 banks and has two independent ports with separate control, address, and I/O pins for each port, allowing each port to access any 2Kx36 memory block not already accessed by the other port. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode.
