11987: Toshiba Launches NAND Flash
Toshiba launched NAND flash at the 1987 IEEE International Electron Devices Meeting in San Francisco. Flash memory (both NOR and NAND types) was invented by Dr. Fujio Masuoka while working for Toshiba around 1980. According to Toshiba, the name “flash” was suggested by Dr. Masuoka’s colleague, Mr. Sho-ji Ariizumi, because the erasure process of the memory contents reminded him of the flash of a camera.
21988: Intel the First to Commercialize NOR Flash
Intel saw the huge potential of the invention and introduced the first commercial NOR-type flash chip in 1988. NOR-based flash has long erase and write times but provides full address and data buses, allowing random access to any memory location. This makes it a suitable replacement for older read-only memory (ROM) chips, which are used to store program code that rarely needs to be updated, such as a computer’s BIOS or the firmware of set-top boxes.

42000: First USB Flash Drive Goes to Market
Trek Technology and IBM began selling the first USB flash drives commercially in 2000. A USB flash drive is a portable plug-and-play data storage device, small enough to be attached to a keychain that can be plugged into any USB port and is immediately recognized by the computer as an external drive. They are also called flash drives, jump drives, memory sticks and thumb drives. Most weigh less than 30 grams. As of January 2012, drives of 256GB were available, 512GB and 1TB drives were in planning; storage capacities as large as 2TB are planned.
52007: Apple Launches Its First iPhone
On Jan. 9, 2007, Jobs announced the iPhone at the Macworld convention, receiving substantial media attention. Of course, the iPhone runs on NAND flash. Since then, dozens of other NAND flash smartphones have come to market, running Android, BlackBerry and other operating systems. iPhones are expected to sell up to 60 million units in 2012 alone.
62008: Toshiba Buys 30 Percent of SanDisks Co-Op Flash Production for $1 Billion
Toshiba, the inventor of NAND flash and SanDisk, partners for several years, announced an agreement that turned over 30 percent of SanDisk’s share of current manufacturing capacity of the companies’ joint ventures to Toshiba. A billion dollars for less than one-third of SanDisk’s business; now, that’s a commitment to NAND flash.
