Abstract: Provided are a memory device storing setting data and a memory system including the same. The memory device may include a cell array including a plurality of cell blocks, each including a plurality of pages, and a control logic that controls a program and read operation on the cell array, wherein at least one page of the cell array stores information data read (IDR) data including information related to a setting operation of the memory device, at least one other page of the cell array stores replica IDR data including inverted bit values of the IDR data, and the control logic controls a recovery operation for repairing errors in the IDR data by reading the replica IDR data when a read fail of the IDR data occurs.

Abstract: An operating method of a storage device includes reading a wear-out pattern of a memory block when a controller determines the memory block is a re-use memory block of a non-volatile memory device; selecting an operation mode corresponding to the read wear-out pattern using the controller; and transmitting the selected operation mode to the non-volatile memory device using the controller.
