ABSTRACT:
There are provided, in addition to an ordinary operation word line for controlling a non-volatile memory upon regularly writing or reading information, a testing word line, a selection transistor, and a storage capacitor, whereby an input signal is transferred onto the testing word line upon inspection to switch on the selection transistor and hence the information is transferred into the capacitor through a bit line for writing into and reading from the capacitor. More specifically, the selection transistor and the capacitor are operated as in a DRAM to diagnose the function of an integrated circuit chip without operation of the non-volatile memory.
