    摘要： A nonvolatile memory device can improve a read retry operation speed while minimizing a reduction in the capability of a memory read operation by performing a read retry operation. The nonvolatile memory device includes a resistive memory cell, a sensing node, and a sense amplifier connected to the sensing node and sensing a difference between a voltage level of the sensing node and a reference voltage level or a difference between a current level of the sensing node and a reference current level. When a read fail bit value is generated during a read operation of data stored in the resistive memory cell, a current flowing in the resistive memory cell is changed by changing a difference between voltages of opposite ends of the resistive memory cell and a read retry operation is then performed.

    摘要： A method of operating a cross-point memory device, having an array of multilevel cells, includes performing a first reading operation with respect to the multilevel cells through a plurality of sensing operations to determine a first state and performing a second reading operation with respect to the multilevel cells through a plurality of sensing operations to determine a second state. A difference between a level of a first voltage used in a first sensing operation and a level of a second voltage used in a second sensing operation in the first reading operation is different from a difference between a level of a third voltage used in a first sensing operation and a level of a fourth voltage used in a second sensing operation in the second reading operation.
