Volatile memory loses its stored data when the power to the memory chip is turned off. "We're working with those companies on the way forward there," U.S. Volatile memory (such as RAM) is the memory that holds the data or information until the power supply to the memory chip is ON. This type of memory is used where data requires to be stored permanently, even when the power is switched, as many memory technologies lose the data once the power is switched. [33][34] Masuoka and colleagues presented the invention of NOR flash in 1984,[35] and then NAND flash in 1987. [29][30] In 1967, Dawon Kahng and Simon Sze of Bell Labs proposed that the floating gate of a MOS semiconductor device could be used for the cell of a reprogrammable read-only memory (ROM), which led to Dov Frohman of Intel inventing EPROM (erasable PROM) in 1971. These FG MOSFETs (or FGMOS in short) have the ability to store an electrical charge for extended periods of time (2 to 10 years) even without a connecting to a power supply. The wafer is showered with ionic gases that modify the conductive properties of the new layer by adding.
