Abstract

PURPOSE: To simplify the circuit constitution, to reduce the power consumption and to make memory information nonvolatile, by collating the memory information with input data with the use of the variable resistance element whose resistance by an applied voltage varies irreversibly and an active semiconductor element of a FET, etc.
