NAND flash memory, the nonvolatile solid-state media that has changed the data storage industry in a profound way, is 25 years old this year. Flash memory 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. Toshiba commercialized NAND flash in 1987; much has changed since then. The NAND flash market has grown rapidly, with flash memory shipping almost eight times more gigabytes in 2011 than DRAM. NAND flash has become the high-density silicon storage of choice. NAND flash memory is used in a variety of memory cards and USB drives, and is found in many consumer, industrial and enterprise cloud applications. This innovation has carved out a path to a new era in which consumers are able to carry videos, music, books and data with them wherever they go. "NAND flash has truly permeated our lives; this technology has been a game changer, making the world a different place and making many of the products we use today possible," said Scott Nelson, vice president of the Memory Business Unit at Toshiba America Electronic Components. "The cost/performance of NAND flash continues to stand the test of time." Go here to read an overview on the history and influence of NAND flash.
 
 
 

1987: 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.
