描述 Description

The 70V7519 is a high-speed 256K x 36 (9Mbit) synchronous Bank-Switchable Dual-Ported SRAM is organized into 64 independent 4Kx36 banks and has two independent ports with separate control, address, and I/O pins for each port, allowing each port to access any 4Kx36 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.
