Renesas Electronics Corporation Memory 7016S15J8

The Quarktwin Technology Ltd. 7016S15J8 is a high-speed dual-ported static RAM with a configuration of 16K x 9 bits. It features true dual-ported memory cells that allow simultaneous reads from the same memory location, making it suitable for applications requiring concurrent access. The device operates with a maximum access time of 12 ns and consumes approximately 750 mW during active operation, with a low standby power consumption of about 1 mW. This memory chip supports cascading to expand data bus widths to 18 bits or more through a master/slave configuration, facilitating integration into wider memory systems without additional discrete logic. It operates asynchronously from either port and is compatible with TTL logic levels, requiring a single 5V (±10%) power supply. The 7016S15J8 is available in a 68-pin PLCC package, and green parts are also offered. The device includes on-chip port arbitration logic and supports semaphore signaling between ports, enhancing its utility in complex memory management scenarios.
