ABSTRACT:
A memory card with a memory element utilizing a CMOS type electric field effect transistor comprises an overcurrent detecting device for detecting the size of current flowing through a power source circuit in order to immediately stop an overcurrent through the power source circuit when a latch-up phenomenon occurs in the memory element and a switch to open the power source circuit when the overcurrent is detected.
