STMicroelectronics (ST) has announced full availability of its entire NAND flash memory family in 70nm process technology.

The transition of the 512Mbit (Small Page) and 1-, 2-, 4- and 8Gbit (Large Page) devices to ST's advanced 70nm manufacturing process establishes the family at the leading edge of NAND flash technology, with lower prices and reduced power consumption.

The high density memory chips are designed to provide mass data storage in a range of computing and consumer applications, such as digital cameras, PDAs, GPS navigation systems, flash cards and USB drives, printers, STBs, digital TV sets, car multimedia systems, and mobile handsets with multimedia features.

All the devices in the family provide ultra-fast data throughput and erase capability, ST said. The Address lines and Data Input/Output signals of all members of the family are multiplexed onto an 8bit or 16bit bus, reducing pin count and allowing the use of a modular NAND interface which enables systems to be adapted to use higher (or lower) density devices without changing the device footprint.

In addition, the devices have a 'Chip Enable Don't Care' feature, which simplifies the microcontroller interface and streamlines the use of NAND flash in combination with other types of memory such as NOR Flash and xRAM.
