Abstract:
1. A memory device, comprising: a sense amplifier configured to amplify a potential difference between a bit line pair; and a sense amplifier drive unit configured to supply the sense amplifier with a pull-up drive voltage and a pull-down drive voltage in response to a pull-up sensing test signal, a pull-down sensing test signal and a termination signal, wherein the sense amplifier drive unit does not supply the pull-down drive voltage when the pull-up sensing test signal is inputted, does not supply the pull-up drive voltage when the pull-down sensing test signal is inputted, and supplies the sense amplifier with both the pull-up drive voltage and the pull-down drive voltage regardless of the pull-up sensing test signal and pull-down sensing test signal when the termination signal is inputted.
