Abstract
A storage device includes a nonvolatile memory device including a memory block and a memory controller. The memory block includes a first memory region connected with a first word line and a second memory region connected with a second word line. The memory controller sets a read block voltage based on a first read voltage of the first memory region. The memory controller determines a second read voltage of the second memory region based on variation information and the read block voltage.
