A five-volt only flash EEPROM technology for high density memory and system IC applications

A CMOS contactless cell array technology has been developed for a single-power-supply high-density, five-V-only flash memory and for system programmable IC applications. The technology's suitability for VLSI memories has been demonstrated by a 256-kb flash EEPROM (electronically erasable programmable read-only memory) chip. This low-current five-V-only approach has been proved, with cell area and cost comparable to recently reported high-current dual-power-supply flash EEPROMs
