WebMOS memory, based on MOS transistors, was developed in the late 1960s, and was the basis for all early commercial semiconductor memory. The first commercial DRAM IC chip, the 1K Intel 1103, was introduced in October 1970. Synchronous dynamic random-access memory (SDRAM) later debuted with the Samsung KM48SL2000 chip in 1992. WebJan 31, 2024 · PROM = programmable read-only memory = can be programmed with a special programmer, but read-only when on the board. EPROM = erasable programmable read-only memory = can be repeatedly programmed with a special programmer, after erasing it with UV light, but read-only when on the board.
