A compact non-volatile memory device and memory array that are compatible with conventional MOS device processing. The compact non-volatile memory device includes a PMOS storage transistor with a floating gate in series with a PMOS access transistor. Since both of these PMOS transistors can be disposed...http://www.google.es/patents/US6414872?utm_source=gb-gplus-sharePatente US6414872 - Compact non-volatile memory device and memory array
