Renesas is the industry’s leading supplier of multi-port memory, offering the most comprehensive line of high-performance dual-port products available.

Our family of multi-port memory is the industry standard, with innovative features and speeds that provide superior value and performance to system-level design. Renesas multiport memory products feature simultaneous access capability, with a number of arbitration techniques available to the designer to prevent contention and system wait states. On-chip hardware arbitration, semaphore token passing and software arbitration allow the designer to select the most efficient multi-port memory for the application.

  • Multi-port solves bus matching issues from x8, x9, x16, x18, x36, up to x72 bit bus widths
  • Multi-port can be used to allow mismatched voltage parts to be used together; 1.8V, 2.5V 3.3V and 5V I/O’s can be adapted
  • Multi-port can buffer bus speed mismatch from DC to 10ns
  • Multi-port densities range from 8 Kb up to 36 Mb, allowing a wide range of applications

About Multi-port Memories
The Renesas multiport memory portfolio includes more than 150 types of asynchronous and synchronous dual-ports, four-ports and bank-switchable dual-ports. These multiport memory devices are ideal for switches, routers, hubs, industrial equipment, fibre channel line cards and RAID controllers.

Renesas multiport memory products are used in avionics, communications, consumer, industrial, medical imaging, and military applications worldwide.

Multi-port memories are commonly used as components in VLSI systems, such as register files in microprocessors, storage for media or network applications. The content of a multiport memory can be accessed through different ports simultaneously. This feature is especially valuable for high-speed processors, media processors, and communication processors. Likewise, multiport memory requires more testing effort since all ports have to be verified.
