ABSTRACT:
A data input circuit outputs input data in accordance with a write enable signal. A program control circuit generates different data items on the basis of the input data output from the data input circuit and the write enable signal, and turns programming transistors on/off in accordance with the different data items as generated. The programming transistors are connected to a pair of cell transistors forming an EPROM cells, and program into these cell transistors the different data items generated by the write control circuit. A timing circuit delays the timing at which the write enable signal is supplied to the write control circuit, until the input data is established within the data input circuit.
