SINGLE CHIP DATA PROCESSOR HAVING EMBEDDED NON-VOLATILE MEMORY COMPOSED OF VARIOUS OPTIMIZED TRANSISTORS

摘要

PURPOSE: A single chip data processor having an embedded non-volatile memory is provided to increase a scale of integrity of a semiconductor device while maintaining a characteristic of the non-volatile memory by using various optimized transistors. CONSTITUTION: A single chip data processor includes a substrate(100), a first well(131), a second well(141), and a non-volatile memory cell. The substrate has a first doping concentration and a first conductive type. The first well is formed on the substrate. The second well has a depth greater than that of the first well and has a doping concentration higher than the first doping concentration and the first conductive type. The non-volatile memory cell is formed on the second well. The non-volatile memory cell is an EEPROM(Electrically Erasable Programmable Read Only Memory).
