Abstract
A resistive memory device may include a resistive cell array and an on-chip resistance measurement circuit. The resistive cell array may include a plurality of resistive memory cells. The on-chip resistance measurement circuit may be configured to generate a first current and a second current greater or less than the first current based on a cell current corresponding to a cell resistance of a first memory cell of the resistive memory cells, and to generate first and second digital signals based on the first and second current, respectively.
