Abstract:
A nonvolatile memory device includes a cell array including a plurality of cell strings extending on a substrate in a vertical direction, a page buffer connected to a plurality of bit lines and configured to store sensing data of the cell array in a sensing operation, a voltage generator configured to provide voltages to a plurality of word lines and the plurality of bit lines, and an input/output buffer configured to temporarily store the sensing data received in a data dump from the page buffer and to output the temporarily stored data to an external device. The nonvolatile memory device further includes control logic configured to set a status of the nonvolatile memory device to a ready state after the sensing data is dumped to the input/output buffer and before recovery of the cell array from a bias voltage of the sensing operation is complete.
Abstract:
Provided are a memory controller and memory system having an improved threshold voltage distribution characteristic and an operating method of the memory system. As a write request of data with respect to a first block is received, an erase program interval (EPI) is determined denoting a time period elapsed after erasure of the first block. When the determined EPI is equal to or less than a reference time, data is programmed to the first block based on a first operation condition selected from among a plurality of operation conditions. When the determined EPI is greater than the reference time, the data is programmed to the first block based on a second operation condition selected from among the plurality of operation conditions.

Abstract:
A nonvolatile memory device includes a voltage generator that sequentially provides a first setup voltage and second setup voltage to a word line of a memory cell array, and control logic including a time control unit that determines a word line setup time for the word line in relation to the second setup voltage based on a difference between the first and second setup voltages.
Abstract:
A nonvolatile memory device may include a memory cell array, an address decoder circuit, a page buffer circuit, and a control logic circuit. An erase operation includes iteratively performing an erase loop which includes an erase section where an erase voltage is applied to the memory cells of the selected memory block and an erase verification section where the memory cells of the selected memory block are verified using an erase verification voltage. If the memory cells of the selected memory block are determined as an erase pass in the erase verification section, the control logic circuit monitors the memory cells of the selected memory block. If the monitored result indicates that the memory cells of the selected memory block are at an abnormal state, the control logic circuit applies an extra erase voltage to the memory cells of the selected memory block.
