nvSRAM Parallel

Cypress’s parallel nvSRAM products are the industry’s fastest parallel nonvolatile RAM solutions with access times as low as 20 ns. They provide unlimited read/write endurance, 1 million STORE cycles on power-loss and an optional Real-Time Clock (RTC). Parallel nvSRAM uses an external Vcap capacitor to complete nonvolatile data transfer on power loss. Unlike battery-backed SRAM (BBSRAM)-based designs, parallel nvSRAM does not require batteries to store data on power loss, which improves reliability while saving cost and board space. Cypress’s parallel nvSRAM products are used in many applications including RAID storage, industrial automation, computing and networking, avionics and defense and electronic gaming systems.
