TOSHIBA – THE INVENTOR OF FLASH MEMORY
In 1984, Toshiba developed a new type of semiconductor memory called flash memory, leading the industry
into the next generation ahead of its competitors.
Some time later in 1987, NAND flash memory was developed, and this has since been used in a variety of
memory cards and electronic equipments. The NAND flash market has grown rapidly, with flash memory
becoming an internationally standardized memory device. Toshiba, the inventor of flash memory, has carved
out a path to a new era in which we are all able to carry videos, music and data with us wherever we go.
