Abstract
The wrong operation preventing circuit is supplied for preventing such accidents as destruction of data, a memory cell section, a sense amplifier and a operation judgement section. The memory cell section is placed at a furthest position from the sense amplifier, the sense amplifier detects the change of voltage on bit line, and the operation judgement section monitors the output of the sense amplifier and outputs a signal for controlling whether the CPU needs to reset.
