Microchip SRAM

SRAM does not require periodic refresh cycles like DRAM, which simplifies the memory controller design and reduces latency. This makes SRAM ideal for embedded applications where deterministic access times and simpler interfaces are more important than raw density. SRAM also typically offers faster access times, making it the preferred choice for cache memory and high-speed data buffering.

Battery-backed SRAM devices include an integrated battery or external battery connection that maintains data when the main system power is removed. The SRAM automatically switches to battery power during a power loss event, preserving the stored data. This provides the speed benefits of SRAM with the non-volatile characteristics typically associated with Flash or EEPROM memory.

Microchip offers serial SRAM with SPI (Serial Peripheral Interface) and SQI (Serial Quad Interface) options. SPI provides a standard 4-wire connection suitable for most embedded applications, while SQI delivers higher throughput by using four data lines simultaneously. These serial interfaces significantly reduce pin count compared to parallel SRAM, enabling smaller package footprints.
