描述
The 5962-86875 (7130/40) is a high-speed 1K x 8 dual-port static RAM designed to be used as a stand-alone 8-bit dual-port RAM or as a "Master" dual-port RAM together with a "Slave" dual-port in 16-bit or more word width systems, which would result in full-speed, error-free operation without the need for additional discrete logic. An automatic power-down feature, controlled by Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode. The military-grade product complies with MIL-PRF-38535 QML.
