Abstract
A variable resistance memory device comprises a variable resistance memory cell, a switch that selectively passes a write voltage to an input terminal of the variable resistance memory cell, and a trigger circuit that controls the switch to cut off the write voltage from the input terminal upon determining that the variable resistance memory cell is programmed to a target state by detecting voltage fluctuation of the one side of variable resistance memory cell.
