Abstract: A method of accessing a nonvolatile memory device which includes a memory block where semiconductor layers including word lines are stacked includes receiving a write request for the memory block, determining whether the write request corresponds to one or more leading word lines, programming, in response to the write request determined as corresponding to the leading word lines, memory cells connected thereto in a first program mode, and programming, when the write request is determined as corresponding to a following word line different from the leading word lines, memory cells connected to the following word line in a second program mode. The second program mode is performed with a second program parameter including at least one of a number of program pulses, a number of program verify pulses, a program start voltage, and a program end voltage that is different from a corresponding first parameter of the first program mode.

Abstract: An operating method of a storage controller which is configured to communicate with a host and with a non-volatile memory device. The method may include: generating an error count by counting a number of first-type error bits of a target super block of the non-volatile memory device, determining whether the error count exceeds a first reference value, fetching setting data from a latch unit of the non-volatile memory device, based on determining that the error count exceeds the first reference value, determining whether reference setting data of a setting table matches the fetched setting data, the reference setting data indicating information about a designed operating environment of the non-volatile memory device, and providing a reset request to the latch unit, based on determining that the reference setting data does not match the fetched setting data.
