Independently programmable memory segments in isolated N-wells within a PMOS EEPROM array

Abstract

An array of P-channel memory cells (401...416) is separated into independently programmable memory segments by creating multiple, electrically isolated N-wells (301,302) upon which the memory segments are fabricated. The methods for creating the multiple, electrically isolated N-wells includes p-n junction isolation and dielectric isolation.
