摘要： A nonvolatile memory device is provided as follows. A memory cell array includes a plurality of memory cells. An address decoder provides a first verify voltage to selected memory cells among the plurality of memory cells in a first program loop and provides a second verify voltage to the selected memory cells in a second program loop. A control logic determines the second program loop as a verify voltage offset point in which the first verify voltage is changed to the second verify voltage based on a result of a verify operation of the first program loop.

摘要： A storage device includes a nonvolatile memory device and a controller configured to generate a read command according to a request of an external host device and transmit the read command to the nonvolatile memory device. The nonvolatile memory device is configured to perform a read operation in response to the read command, to output read data to the controller, and to store information of the read operation in an internal register.
