Abstract: A nonvolatile memory device includes a memory cell array having a normal area and a temporary area. A page buffer stores data to be written to the normal area in a normal program operation and store a temporary data to be written to the temporary area in a temporary program operation. A control logic performs the normal program operation including a plurality of program loops. The control logic receives a suspend command before the normal program operation is completed and determines, in response to the suspend command, whether to complete the normal program operation or to suspend the normal operation and perform the temporary program operation based on a reference value representing a time for performing at least one program loop of the plurality of program loops.

Abstract: An operating method of a multi-bit-per-cell nonvolatile memory device, e.g., first and second variable resistance memory cells connected to one of word lines. The operating method may include receiving first to fourth data sequentially, providing a first program current to the first variable resistance memory cell to program the first and second data to the first variable resistance memory cell, and providing a second program current to the second variable resistance memory cell to program the third and fourth data to the second variable resistance memory cell after verifying whether an actual resistance of the programmed first variable resistance memory cell is within an intended resistance distribution.
