EEPROM CIRCUIT

An EEPROM circuit has two memory transistors in a memory cell of an array. Stored data is read out to a reading circuit via a first and second complementary bit lines. A writing circuit provides voltage to the cell so that the first memory transistor writes data and the second memory transistor erases data. An erasing circuit does the converse, i.e. provides voltage to the cell so that the first memory transistor erases data and the second memory transistor writes data.
