Abstract
A nonvolatile memory system includes a nonvolatile memory device and a memory controller that controls the nonvolatile memory device. The nonvolatile memory device includes multiple memory blocks. Each of the memory blocks includes memory cells. Each of the memory cells has any one of an erase state and one of multiple different program states. An operation method of the nonvolatile memory system includes receiving a physical erase command from an external device. The operation method also includes performing a fast erase operation, responsive to the received physical erase command, with respect to at least one memory block so that first memory cells of the at least one memory block have a fast erase state different from the erase state.
