70261L12PF

Memory IC Overview

The Renesas Electronics Corporation 70261L12PF is a high-speed 16K x 16 Dual-Port Static RAM designed for standalone or master/slave configurations in 32-bit systems. It features true dual-ported memory cells allowing simultaneous access to the same location, separate upper and lower byte controls for multiplexed bus compatibility, and on-chip port arbitration logic with semaphore signaling support. The device operates asynchronously from either port using a single 5V power supply and includes automatic power-down features controlled by chip enable signals.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations
• On-chip hardware support for semaphore signaling and port arbitration between ports
• Separate upper-byte and lower-byte control lines compatible with multiplexed bus systems
• Automatic low standby power mode activated via chip enable signal control

Memory IC Applications

• Standalone dual-port memory applications
• Master/slave dual-port RAM combinations for 32-bit or wider word systems
• High-speed data buffering requiring concurrent port access
