Abstract

The present invention relates to a method of making a multibit non-volatile memory and especially to a method of making a flash memory such as a fast-programmable Flash EEPROM (Electrically Erasable Programmable Read-Only Memory) device relying on hot-electron injection for programming which is particularly suited for high density low-voltage low-power applications and employs only two polysilicon layers.
