Abstract
A data storage device includes a nonvolatile memory device and a controller configured to control an operation of the nonvolatile memory device. The controller includes an RAM in which a category table that categories with respect to LBAs are defined and a read voltage table that read voltages with respect to the categories are set are stored and a controller configured to, when a read request and an LBA to be read are received from a host apparatus, determine a category corresponding to the LBA with reference to the category table and perform a read operation on a read-requested memory cell of the nonvolatile memory device by applying a read voltage corresponding to the determined category to the memory cell with reference to the read voltage table.
