"As technologies move down the scaling curve, conventional floating gate Flash memory is running out of steam at 45nm processes and below. Many companies are proposing charge-trapping technologies as an option," said Jim Handy, Director of Objective Analysis. "Spansion has had a charge trapping process in production for four years, giving the company a big head start on its competitors. The company's next-generation MirrorBit ORNAND2 architecture, a NAND array based on a SONOS-like cell structure, will further use this leadership to expand Spansion's market opportunities into areas currently served by NAND alone."

Flash memory (both NOR and NAND types) was invented by Dr. Fujio Masuoka while working for Toshiba in 1984. According to Toshiba, the name "flash" was suggested by Dr. Masuoka's colleague, Mr. Shoji Ariizumi, because the erasure process of the memory contents reminded him of a flash of a camera. Dr. Masuoka presented the invention at the IEEE 1984 International Electron Devices Meeting (IEDM) held in San Francisco, California. Intel saw the massive potential of the invention and introduced the first commercial NOR type flash chip in 1988.

Toshiba, the world's no. 2 maker of NAND-type flash memory, will start building flash-based solid-state drives (SSDs) for notebooks to create new sources of demands for its flash memory chips. Samsung Electronics, the world's biggest memory chip maker, and SanDisk (Toshiba's partner) already make SSDs.

Within the past couple of years, Intel has expanded its products to include flash memory chips. The company is working on a flash chip called Robson--expected within the year--that is ... designed to work with Vista features. As with Samsung's hybrid drive, Intel's system will be able to save energy by less frequently using a hard diskby keeping a cache in flash, says Greg Matson, product manager for Intel's NAND flash group. Robson is designed for consumer and enterprise systems that run Vista. Unlike Samsung's hybrid drive, which integrates flash into the disk, Robson flash will be integrated into the motherboard of a computer.
