Core Product Series
1. Smart Memories FRAM (Ferroelectric RAM)
FRAM combines the fast read/write capability of DRAM with the non-volatile feature of ROM. Key features include high-speed operation (SPI FRAM 25MHz/I2C FRAM 1MHz), ultra-low power consumption (92% lower than EEPROM), and ultra-high durability (up to 10¹³ read/write cycles).
