Ramtron to show new FRAM at electronica

Ramtron´s new FRAM memory FM25L256 makes European debut at electronica 2004.
In addition to the FRAM memory Ramtron releases an FRAM-based Processor Companion family called FM32x and FM2005, a standalone Processor Companion device.

The FM25L256 is a 256-Kilobit (Kb), 3V non-volatile FRAM device with a serial peripheral interface (SPI) . The FM25L256 reads and writes at bus speeds comparable to those of a high-speed RAM, but provides non-volatile storage like a conventional non-volatile memory. It also offers 25MHz NoDelay writes so, unlike EEPROM or Flash, no write delays are incurred. Like high-speed RAM, the FM25L256 supports an unlimited number of read or write cycles, whereas EEPROM wears out after approximately one million cycles. The device operates from 2.7V to 3.6V.

The FM32x Processor Companion family combines a non-volatile FRAM with a processor supervisor. The FM32x Processor Companion family offers a choice of 4Kb (FM3204), 16Kb (FM3216), 64Kb (FM3264), or 256Kb (FM32256) of non-volatile FRAM with a processor supervisor that features a programmable low-VDD reset, a programmable watchdog timer and a manual reset function. All devices operate from 2.7V to 5.5V

Ramtron announced that all these devices are now shipping in pre-production volumes.
