NONVOLATILE MEMORY DEVICE, STORAGE DEVICE INCLUDING THE NONVOLATILE MEMORY DEVICE, AND OPERATING METHOD OF THE STORAGE DEVICE

摘要

A storage device includes a nonvolatile memory device and a memory controller is provided. The nonvolatile memory device includes a plurality of blocks. The memory controller is configured to detect, upon receiving a power-on signal, a partial block among the plurality of blocks. The partial block includes a first page incompletely programmed due to sudden power-off occurred to the storage device. The memory controller determines whether or not to perform a dummy program operation on the partial block, and programs a second page of the partial bock with dummy data. The first page is different from the second page.
