High-density nvSRAMs challenge Fast SRAM territories

Non-volatile SRAM (nvSRAM) combines back-up protection with Fast-SRAM performance, and Simtek is adding high density to these advantages by introducing the STK14EC8/16 and STK14EE8/16 nvSRAMs in 4Mbit and 8Mbit densities respectively.

Four devices are available in x8 and x16 data widths. The 8Mbit x16 memories also provide a convenient building block for 16Mbit nvSRAMs in 32-bit systems. The x8 products are available in either 44-pin TSOPII or 48-pin BGA packages, while x16 devices are offered in 54-pin TSOPII or 48-pin BGA. Read-access and read/write cycle-time grades are 25ns and 45ns, and both commercial and industrial temperature ranges are available.

nvSRAM devices replace fast SRAM in high-speed processor systems. Advantages include reduced wait states and optimal performance, as well as the added benefit of backup protection for critical system-state information. Whereas traditional fast SRAM or battery-backed SRAM solutions impose constraints on designers, Simtek’s nvSRAMs deliver unlimited read/write endurance, automatic store on power-loss, automatic recall on power-up and unlimited recall cycles.
