Abstract
A memory device includes a memory cell array including a plurality of memory cells, each including a bidirectional variable resistance element and an input/output circuit configured to determine a polarity for a read voltage to be applied to a selected memory cell among the plurality of memory cells and to apply the read voltage with the determined polarity to the selected memory cell. The input/output circuit may include a polarity determination circuit configured to determine the polarity responsive to a determination mode signal and a driver circuit configured to apply the read voltage with the determined polarity to the selected memory cell.
