Asynchronous SRAMs

Renesas asynchronous SRAMs are reliable, high-performance memory solutions for applications that require cost-effective, high-speed capabilities. Built with advanced CMOS technology, these SRAMS feature fully static asynchronous circuitry, operating without clocks or refresh cycles to ensure efficiency and simplicity. Offered in RoHS-compliant packaging and industry-standard options, they are ideal for a range of uses—from CPU cache memory and hard drive buffers to networking equipment and consumer electronics.

Choosing an Asynchronous SRAM

Density: Number of bits the asynchronous SRAM can store. Renesas devices feature configurations with capacities of up to 4MB.
Bus Width: Number of "lanes" used for reading and writing data. We offer both 8-bit and 16-bit options.
Core Voltage: Supply voltage powering the the asynchronous SRAM is typically determined by available power rails. We support standard 5V and 3.3V options.
I/O Voltage: Voltage used for data input and output is separate from core voltage in some devices.
Access Time: How quickly the SRAM can perform read or write operations. Our asynchronous SRAMs deliver access times as fast as 10ns.
