特長
- True dual-ported memory cells allow simultaneous access of the same memory location
- Versatile control for write: Separate write control for the lower and upper byte of each port
- Easily expands data bus width to 32 bits or more using Slave
- On-chip port arbitration logic
- BUSY input
- Fully asynchronous operation from either port
- Battery backup operation – 2V data retention
- TTL-compatible; single 5V (±10%) power supply
- Available in 68-pin ceramic PGA and Flatpack packages
説明
The 5962-88610 (7133/43) is a high-speed 2K x 16 dual-port static RAM. Using the Master/Slave dual-port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. The military-grade product complies with MIL-PRF-38535 QML.
