PASS/FAIL CHECK CIRCUIT CAPABLE OF ACCURATELY CHECKING PASS/FAIL

摘要

PURPOSE: A pass/fail check circuit is provided to reduce an area thereof by using a sensing node without an additional capacitor.;CONSTITUTION: A first capacitor unit(310) includes a plurality of first capacitors which is activated or inactivated in response to a plurality of verification completion data. The first capacitor unit has capacitance determined by activated capacitors among the plurality of the first capacitors. A second capacitor unit(320) has preset capacitance. A pass/fail signal generating unit(330) generates a pass/fail signal by comparing the capacitance of the first capacitor unit with the capacitance of the second capacitor unit.;COPYRIGHT KIPO 2012
