SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit that can be obtained by a standard CMOS process capable of achieving microfabrication and operate with high voltage.SOLUTION: A data node NA is connected with a bit line to which a nonvolatile memory cell to be accessed is connected among a plurality of bit lines BTIj. A data control transistor 1 is interposed between a power source node VPP and a write voltage generation node NW. A data control switch 2 is interposed between the write voltage generation node NW and the data node NA. An input circuit 20 switches the on/off state of the data control switch 2 in accordance with a data signal Dinh. A write circuit 10 controls a gate voltage of the data control transistor 1 in accordance with a write signal WE, and in doing so, suppresses a voltage to be applied to the write voltage generation node NW by a gate voltage for the data control transistor 1.
