FRAM

FRAM(Ferroelectric Memory) has advantages of non-volatile memory like E²PROM, keeping write data without power supply for data retention, and high-speed write performance of SRAM. FRAM has 2 product families; serial interface (I²C, SPI) and parallel interface product. FRAMs with Serial I/F are replaceable with serial E²PROM or serial flash memory, and products with parallel I/F are replaceable with low power SRAM or pseudo SRAM(PSRAM).

Fujitsu Semiconductor group controls whole processes of FRAM; development of chip, mass production in Japan, and assembly process. Fujitsu assures high quality and stable supply of FRAM product. Since year 1999, FRAM products have been shipping more than 12 years and are offering many customers requesting high reliability.

FRAM products of 4Kbit to 4Mbit are now available in production. Fujitsu is offering the engineering samples or production samples for customer evaluation. Please confirm our FRAM Product Lineup and request us samples and/or documents by the "FRAM Sample/Document Requests & Inquiry Form" if you would like to have.
