发明名称 EEPROM MEMORY CELL WITH FIRST-DOPANT-TYPE CONTROL GATE TRANSISTOR, AND SECOND-DOPANT TYPE PROGRAM/ERASE AND ACCESS TRANSISTORS FORMED IN COMMON WELL
摘要 A memory device including a plurality of memory cells, each with a control gate NMOS transistor sharing a floating gate with a program/erase PMOS transistor which is, in turn, connected in series with an access PMOS transistor. The memory cells are formed in a common N-Well formed in a P-substrate, the NMOS transistor being formed in a p-doped pocket or base. The program/erase PMOS includes a gate, and first and second P+ doped regions formed in the N-Well, wherein the first P+ region is electrically connected to a corresponding bit line. The access PMOS includes a gate, and first and second P+ regions formed within the N-Well, wherein the first P+ region is electrically connected to the second P+ region of the program/erase PMOS, and the gate is electrically connected to a corresponding word line. The control gate NMOS includes source, drain, and gate, wherein the source and third drain as well as the p-doped pocket are electrically connected to a corresponding control gate line, and the gate is electrically connected to the gate of the program/erase PMOS, forming floating gate of the cell.
