Abstract
A semiconductor device includes a control circuit configured to deactivate a word line during an active operation during a test mode, generate a matching control signal and a sense amplifier drive signal, and activate the word line after a settling period during the test mode, and a sense amplifier configured to drive a bit line and an inverted bit line to a same voltage level based on the matching control signal during the mismatching cancellation operation, and sense and amplify a voltage difference between the bit line and the inverted bit line based on the sense amplifier drive signal when the word line is activated after the settling period during the test mode.
