Ramtron

Ramtron International Corporation, commonly known as Ramtron, was an American semiconductor company that developed non-volatile memory technologies, most notably ferroelectric RAM (FRAM). FRAM memories store data using a ferroelectric layer, enabling non-volatile storage with fast write times, low power consumption, and exceptionally high write endurance compared with traditional flash memory. Ramtron offered standalone FRAM devices as well as embedded memory IP licenses, targeting applications in automotive, industrial, medical, and consumer electronics.

Technology and products centered on FRAM, a memory type that combines the speed of DRAM with the data retention of flash. The technology is suitable for frequent-write environments where power efficiency and endurance are critical, such as data-logging, sensor networks, and embedded systems. Ramtron promoted both discrete FRAM parts and memory solutions designed for integration into larger systems.

History and corporate trajectory: Ramtron grew as a supplier of FRAM technology and held a public listing on the NASDAQ under the RMTR ticker. In 2012, the company announced an acquisition by Fujitsu Limited, with the transaction subsequently completed, integrating Ramtron’s FRAM technology into Fujitsu’s non-volatile memory portfolio. Following the acquisition, the Ramtron brand and operations were folded into Fujitsu, and the FRAM business continued under Fujitsu’s memory products umbrella.

Legacy: Ramtron contributed to the broader development and commercialization of FRAM as a non-volatile memory option. While the standalone Ramtron entity and brand ceased after the acquisition, its FRAM technology has continued to influence embedded memory strategies within Fujitsu and the wider industry, offering an alternative to flash for applications requiring high endurance and rapid writes.
