7015数据手册Renesas中文资料规格书

描述 Description

The 7015 is a high-speed 8K x 9 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 18-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18- 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.
