Abstract:
A variable resistance memory device comprises a variable resistance memory cells and a read/write circuit configured to provide a program voltage to the variable resistance memory cell, and further configured to adjust a compliance current flowing through the variable resistance memory cell in successive loops of a program operation.
Abstract:
A method of operating a variable resistance memory device comprises determining a level of an access voltage based on a number of rows or columns of a cell array, and supplying the access voltage having the determined level to the cell array.
Abstract:
A method of operating a nonvolatile memory device is provided as follows. The nonvolatile memory device includes memory blocks each of which has word lines. A setup voltage is applied to the word lines. A word line voltage is applied to a first word line selected from the word lines. Recovery voltages are applied to the word lines. Each recovery voltage is applied to at least one corresponding word line of the word lines. The recovery voltages have different voltage levels from each other.
