NV RAM (FRAM, MRAM, nvSRAM)

NVRAM (Non-Volatile Random-Access Memory) ICs encompass advanced memory technologies — including FRAM (Ferroelectric RAM), MRAM (Magnetoresistive RAM), and nvSRAM — designed to combine the near-instantaneous read/write speeds, byte-addressability, and infinite write endurance of SRAM with non-volatile data retention through power outages. These devices represent the premier solution for real-time data logging, telemetry capture, and configuration protection in utility meters, medical equipment, and industrial controllers.

FRAM utilizing ferroelectric polarization offers write speeds in nanoseconds and extreme write endurance (exceeding 10^13 cycles), while MRAM utilizing magnetic tunneling junctions offers high density and radiation immunity. Selection criteria focus on memory density, access speed, serial interface (SPI, I2C) or parallel bus, current consumption, and operating voltage rails.
