    Abstract: Provided are a non-volatile memory device and an erasing method thereof. The erasing method of the non-volatile memory device including a plurality of cell strings in which memory cells and selection transistors are connected, includes: performing a first erase operation based on an erase voltage provided to a first electrode of at least one of the selection transistors and an erase control voltage provided to a second electrode of the at least one of the selection transistors; determining whether there are slow erase cells by performing a multiple erase verify operation based on first and second verify voltages, the second verify voltage being higher than the first verify voltage; adjusting, when there are slow erase cells, the erase control voltage such that a voltage difference between the erase voltage and the erase control voltage increases; and performing a second erase operation based on the adjusted erase control voltage.

    Abstract: Nonvolatile memory device includes a memory cell array including pages, each of the pages including memory cells storing data bits, each of the data bits being selectable by a different threshold voltage, a page buffer circuit coupled to the memory cell array through bit-lines, the page buffer circuit including page buffers to sense data from selected memory cells, and perform a first read operation and a second read operation, each including two sequential sensing operations to determine one data state, and each of the page buffers including a latch configured to sequentially store results of the two sequential sensing operations, and a control circuit to control the page buffers to store a result of the first read operation, reset the latches after completion of the first read operation, and perform the second read operation based on a valley determined based on the result of the first read operation.
