    Abstract: The nonvolatile memory device using a variable resistance material and a method for driving the same are provided. A first clamping unit connected between a resistance memory cell and a first sensing node to provide a first clamping bias to the resistance memory cell. The first clamping bias changes over time. A first compensation unit provides a compensation current to the first sensing node. A first sense amplifier is connected to the first sensing node to sense a level change of the first sensing node. In response to if first data stored in the resistance memory cell, an output value of the first sense amplifier transitions to a different state after a first amount of time from a time point from where the first clamping bias starts. In response to second data that is different from the first data stored in the resistance memory cell, the output value of the first sense amplifier transitions to the different state after a second amount of time that is different from the first amount of time from the time point from where the first clamping bias starts.

    Abstract: A method of operating a memory device includes determining a value of an operating current flowing through a selected first signal line, to which a selection voltage is applied, from among a plurality of first signal lines; dividing an array of memory cells into n blocks, n being an integer greater than 1, based on the value of the operating current; and applying inhibit voltages having different voltage levels corresponding to the n blocks to unselected ones of second signal lines included in the n blocks. Each of the unselected second signal lines is a pathway through which leakage current may potentially flow due to the operating current flowing through the selected first signal line and a memory cell addressed by the unselected second signal line and the selected first signal line.
