Ramtron samples 64Kb 20MHz bus-speed serial SPI FRAM chips

Ramtron International Corporation has announced pre-qualification sampling of a new family of 4- to 64-Kilobit (Kb) serial nonvolatile ferroelectric RAM (F-RAM) products. Produced on Ramtron's ferroelectric memory process at its new U.S. wafer source. The new products feature 1-trillion (1e12) read/write cycles, low power consumption, and NoDelay writes.

The FM25040C, FM25C160C, and FM25640C are 4-, 16-, and 64-Kilobit (Kb) memory devices that perform write operations at bus speeds of up to 20MHz with an industry standard Serial Peripheral Interface (SPI). Data is written to the F-RAM memory array immediately after it is received by the device.
