70V34 - Block Diagram
説明
The 70V34 is a high-speed 4K x 18 Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.
