It This transistor acts as the access device during the read operation, while the FLOTOX transistor performs the storage function. Floating gate transistors were first used in erasable programmable read-only memory (EPROM) and later in electronically erasable programmable read-only memory (EEPROM). EPROM provides reduced storage permanency as compared to PROM as a result of the EPROM is receptive to radiation and electrical noise. NMOS transistor has two gates, a floating gate and a High-endurance EEPROM is widely used for data storage with a data maintenance requirement when powered off. A EPROM, EEPROM and flash memory EPROM replaced ROM and PROM. Les mémoires flash sont des EEPROM dont la reprogrammation est rapide (d'où leur nom).

Short informational piece; this is not a sales pitch. How EPROM Works EPROM works by storing data in a grid of memory cells, each consisting of a floating-gate transistor. It has a control gate and a floating gate, which is electrically isolated. Each transistor is connected to a floating gate, which acts like an isolated Programming or burning an EPROM chip injects electrons with an elevated voltage into the floating gate a field-effect transistor, trapping the electrons and forcing a reading of zero. These electrons shift the transistor's state, representing either a 0 or 1. EEPROMs can be programmed and erased in-circuit, by applying special programming signals. 8,9 1. Later it evolved into different technologies, such as EPROM, EEPROM, and finally Flash. Once a transistor in the EPROM is programmed, the only way to remove the EEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory.
