Abstract
PURPOSE: To enable the optional inversion of polarity, by providing an inversion circuit on the output side of a pattern generation circuit.
CONSTITUTION: An inversion circuit 4 comprising a plurality of exclusive OR circuits 4aW4n is provided between a pattern generation circuit 1 and a tested element 2. A setting circuit 5 comprising a register 5a and a group 5b of AND gates is connected to the inversion circuit 4. When an inversion instructing signal P1 is set to a logic value "1" at optional time, the polarity of a pattern signal applied to the tested element 2 at that time is inverted only with regard to a bit set by the setting circuit 1. The polarity of a desired bit can thus be optionally inverted at desired time without providing a the pattern generation circuit 1 with a program for inverting the polarity at the desired time. This enables easily and accurately testing the memory element.
