Erasable Programmable Read-Only Memory

In fall 1969, Intel was having reliability problems with its 1101 static random access -only memory (SRAM), the first mass-produced chip to use metal-oxide semiconductor technology. Dov Frohman, a recent arrival to Intel from Fairchild Semiconductor, was asked to investigate the problem. His findings would lead him to invent erasable programmable read-only memory (EPROM).
