摘要：A data processing device which selects either emission of electrons from anonvolatile memory cell or injection of electrons into it for each bit. A memory arrayincludes a plurality of nonvolatile memory cells each having a pair of a first MOStransistor and a second MOS transistor where the first transistor has a charge retention

layer and a memory gate and is used for data storage and the second transistor has acontrol gate and selectively connects the first transistor to a bit line. When negativevoltage is applied to a memory gate, electrons held by a charge retention layer areemitted through hot carriers generated in a nonvolatile memory cell channel region forerasing; and when positive voltage is applied to the memory gate, electrons are injectedinto the charge retention layer through hot carriers generated in the nonvolatile memorycell channel region for writing and controls the generation and suppression of hotcarriers by means of bit line voltage on each bit line.
