Nonvolatile memory claims lowest energy consumption

Nonvolatile ferroelectric random access memory supplier (FRAM) Ramtron International Corp. has released a low energy non-volatile memory product.

Ramtron's FM25P16 is a 16-kilobit serial non-volatile memory that opens up new possibilities in power-sensitive system design, claiming to have the industry's lowest energy consumption in a non-volatile memory device. As the first member of the Ramtron Low Energy Memory family, the FM25P16 uses 1/1,000th the energy of electrically erasable programmable read-only memory (EEPROM) devices, while delivering fast read/write performance and virtually unlimited endurance.


The FM25P16 uses a fast serial peripheral interface, operating up to full bus speed of 1MHz frequency.

"The fast write ability of nonvolatile F-RAM combined with an innovative IC design has enabled us to achieve the lowest energy consumption to date in a nonvolatile memory device with a typical active current of about 3 microamps," said Scott Emley, Ramtron vice president of marketing. "Using Ramtron Low Energy memory products, power sensitive systems including wireless sensor nodes, remote metering, health and fitness products, as well as emerging energy harvesting applications can write data orders of magnitude more frequently while lowering system power."

According to the company, the benefit of Ramtron low energy memory increases significantly as the system writes data more frequently. Unlike serial EEPROMs, FM25P16 can perform fast and power-efficient write operations at bus speed with no write delays. These capabilities make FM25P16 ideal for nonvolatile memory applications requiring both very low power and frequent or rapid writes.

The FM25P16 employs an advanced ferroelectric process that yields virtually unlimited endurance of 100-trillion (1e14) read/write cycles and reliable data retention for 10 years. The FM25P16 uses a fast serial peripheral interface (SPI), operating up to full bus speed of 1MHz frequency.

The FM25P16 is now sampling in limited quantities with an expected resale unit price of $0.99 in 10K volume.
