Standalone FRAM
FRAM has what it takes to become the non-volatile memory of the future and to supersede both Flash and E2PROM. With its low power consumption, the technology combines the benefits of conventional non-volatile memories and rapid static RAM.
FRAM combines the benefits of Flash / E2PROM and SRAM / DRAM
