Abstract
A reference apparatus for determining a current or voltage of a semiconductor device, includes a plurality of reference cells having threshold values different from each other, and a selection circuit for selecting one of the plurality of reference cells. A current flowing in a semiconductor device can be determined by comparing the current flowing in the reference apparatus, with the current flowing in a semiconductor cell by means of a sense amplifier.
