Abstract: A method of operating a non-volatile memory device includes performing a first sensing operation on the non-volatile memory device during a first sensing time including a first section, a second section, and a third section. The performing of the first sensing operation includes applying a first voltage level, which is variable according to a first target voltage level, to a selected word line in the first section, applying a second voltage level, which is different from the first voltage level, to the selected word line in the second section, and applying the first target voltage level, which is different from the second voltage level, to the selected word line in the third section. The first voltage level becomes greater as the first target voltage level becomes greater.

Abstract: A method of operating a nonvolatile memory device includes erasing data within a NAND string of memory cells within the memory device by applying a non-zero erase voltage to a source/drain terminal at a first end of the NAND string. This erase voltage is applied concurrently with establishing gate-induced drain leakage (GIDL) in a pair of selection transistors within the NAND string. This GIDL can occur by applying unequal and non-zero first and second voltages to respective first and second gate terminals of the pair of selection transistors. The selection transistors can be string selection transistors or ground selection transistors.

Abstract: A nonvolatile memory device includes a memory cell array, a voltage generator, a page buffer circuit, a row decoder and a control circuit. The memory cell array includes a plurality of mats corresponding to different bit-lines. The voltage generator generates word-line voltages applied to the memory cell array. The page buffer circuit is coupled to the memory cell array through bit-lines. The row decoder is coupled to the memory cell array through word-lines, and the row decoder transfers the word-line voltages to the memory cell array. The control circuit controls the voltage generator, the row decoder and the page buffer circuit based on a command and an address. The control circuit selects a voltage between different voltages to apply the selected different voltages to at least one of the word-lines or at least one of the bit-lines according to a number of mats of the plurality mats, which operate simultaneously.

Abstract: A nonvolatile memory device includes a memory cell array, a row decoder, a page buffer, and control logic. The memory cell array includes memory cells connected to word lines and bit lines, the memory cell array being configured to store data. The row decoder is configured to selectively activate a string selection line, a ground selection line, and the word lines of the memory cell array. The page buffer is configured to temporarily store external data and to apply a predetermined voltage to the bit lines according to the stored data during a program operation, and to sense data stored in selected memory cells using the bit lines during a read operation or a verification operation. The control logic is configured to control the row decoder and the page buffer. During execution of commands, when a request to suspend the execution of the commands is retrieved, chip information is backed up to a storage space separate from the control logic.
