Flash memory goes mainstream

The operation of the flash memory, which has matured over the last five years from a novelty product, is described. Both dual and single supply voltage devices are considered. Flash memory cycling, data reliability, program/erase algorithms, and blocking are discussed. Three approaches to flash memories are examined. The uses of these devices and some new architectures are considered.<<ETX>>

Designing an updatable BIOS using flash memory

Flash memory offers the same non-volatile storage as EPROM but also provides in-system write capability. Using Intels 28F001BX for BIOS storage, code updates may be carried out quickly in the factory during test and debug, while allowing cost-effective field updates to end users via floppy discs or modem BBS. This application note describes various methods of implementing a flash memory BIOS using the 28F001BX. Design targets are both laptop and desktop systems. The primary emphasis is on application of flash memory for BIOS and ROM executable software applications.

Performance benefits and power/energy savings of 28FOl6XS-based system designs

Abstract This application note discusses the performance and power/energy comparisons between Intels 28F016XS flash memory and other memory technologies, and the positive impacts on system performance and power consumption.
