According to <a href="http://en.wikipedia.org/wiki/Toshiba" target="_blank">Toshiba</a>, 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 <a href="http://en.wikipedia.org/wiki/Flash_%28photography%29" target="_blank">flash</a> of a camera. Dr. Masuoka presented the invention at the <a href="http://en.wikipedia.org/wiki/IEEE" target="_blank">IEEE</a> 1984 International Electron Devices Meeting (IEDM) held in San Jose, California. <a href="http://en.wikipedia.org/wiki/Intel" target="_blank">Intel</a> saw the massive potential of the invention and introduced the first commercial NOR type flash chip in <a href="http://en.wikipedia.org/wiki/1988" target="_blank">1988</a>. while working for  NOR-based flash has long erase and write times, but has a full address/data (memory) interface that allows <a href="http://en.wikipedia.org/wiki/Random_access" target="_blank">random access</a> to any location. This makes it suitable for storage of program code that needs to be infrequently updated, such as a computer's <a href="http://en.wikipedia.org/wiki/BIOS" target="_blank">BIOS</a> or the <a href="http://en.wikipedia.org/wiki/Firmware" target="_blank">firmware</a> of <a href="http://en.wikipedia.org/wiki/Set-top_box" target="_blank">set-top boxes</a>. Its endurance is 10,000 to 1,000,000 erase cycles. NOR-based flash was the basis of early flash-based removable media; <a href="http://en.wikipedia.org/wiki/Compact_Flash" target="_blank">Compact Flash</a> was originally based on it, though later cards moved to the less expensive NAND flash. NAND flash, which <a href="http://en.wikipedia.org/wiki/Toshiba" target="_blank">Toshiba</a> announced at <a href="http://en.wikipedia.org/wiki/ISSCC" target="_blank">ISSCC</a> in <a href="http://en.wikipedia.org/wiki/1989" target="_blank">1989</a>, followed. It has faster erase and write times, higher density, and lower cost per bit than NOR flash, and ten times the endurance. However its I/O interface allows only <a href="http://en.wikipedia.org/wiki/Sequential_access" target="_blank">sequential access</a> to data. This makes it suitable for mass-storage devices such as <a href="http://en.wikipedia.org/wiki/PCMCIA" target="_blank">PC cards</a> and various <a href="http://en.wikipedia.org/wiki/Memory_card" target="_blank">memory cards</a>, and somewhat less useful for computer memory. The first NAND-based removable media format was <a href="http://en.wikipedia.org/wiki/SmartMedia" target="_blank">SmartMedia</a>, and numerous others have followed: <a href="http://en.wikipedia.org/wiki/Multi_Media_Card" target="_blank">MMC</a>, <a href="http://en.wikipedia.org/wiki/Secure_Digital" target="_blank">Secure Digital</a>, <a href="http://en.wikipedia.org/wiki/Memory_Stick" target="_blank">Memory Stick</a> and <a href="http://en.wikipedia.org/wiki/XD-Picture_Card" target="_blank">xD-Picture Cards</a>. A new generation of these formats is becoming a reality with RS-MMC (Reduced Size MultiMedia Card), the micro- and miniSD variants of Secure Digital and the new USB/Memory card hybrid <a href="http://en.wikipedia.org/wiki/Intelligent_Stick" target="_blank">Intelligent Stick</a>. The new formats exhibit a greatly reduced size, usually under 4 cm².</blockquote>
