Abstract
A memory device, and a method of operating the memory device, includes a memory block, a peripheral circuit, an erase controller, and a parameter setter. The memory device includes a plurality of sub blocks. The peripheral circuit performs an erase operation on a target sub block among the plurality of sub blocks. The erase controller controls the peripheral circuit to perform the erase operation based on a default parameter or an optimal parameter according to a group to which the target sub block belongs among first, second, and third groups. The parameter setter sets the optimal parameter based on a result of the erase operation when the target sub block is included in the first group or the third group.
