1Mbit Non-Volatile RAM Lowers Voltage and Increases Performance

The FM25V10 is a Ferroelectric Random Access Memory (F-RAM) designed to offer high-speed read and write performance, with low-voltage operation and other features.

This performance is being offered with a memory density of 1Mbit, enabled by Ramtron’s high-density F-RAM manufacturing process.

Operating from 2V to 3.6V, the FM25V10 is a non-volatile, SPI-based RAM which features fast access, NoDelay™ writes, 1014 read or write cycles, and low power consumption. It can therefore be considered as an upgrade to 1Mbit serial Flash and serial EEPROM memories.

Unlike serial Flash memory or serial EEPROM, the FM25V10 performs write operations at bus speed without write delays. Compared to serial Flash and serial EEPROM, the FM25V10 also offers more than eight orders of magnitude more endurance, and consumes less than one-tenth of the active power.

The FM25V10 is the first in Ramtron’s V-Family of F-RAM products. These memory devices integrate features designed to reduce board space as well as assembly and device costs. The FM25V10 has a read-only device ID, and can be provided with a unique serial number and system-reset option. The device ID provides information about the manufacturer, product density and product revision of the device.

The FM25V10 operates over the industrial temperature range from -40°C to 85°C, and consumes only 3mA while running at a 40MHz SPI clock rate. It consumes just 90mA during standby and 5mA during sleep mode.

The FM25V10 offers an active power consumption of 38mA per MHz, which is significantly lower than comparable serial Flash or EEPROM products.

Ramtron also offer a 512kbit F-RAM, the FM25V05, and have road-mapped versions with SPI, I²C and parallel interfaces.
