ABSTRACT:
A data write apparatus for nonvolatile memory includes a control device for transmitting or receiving data, and a nonvolatile memory connected to the control device through a communication line, for storing the data supplied from the control device. The nonvolatile memory permits write of data if the number of pulses of a clock signal transmitted as well as the data agrees with a prescribed number and the nonvolatile memory inhibits write of data if the number of pulses of the clock signal does not agree with the prescribed number of pulses. The control device includes a receiving member for receiving the data transmitted onto the communication line; and an increasing/decreasing member for comparing a first data supplied to the nonvolatile and a second data received by the receiving member through the communication line to determine whether or not the first data and the second data are the same data.
