Abstract
A storage device may include a memory device and a memory controller. The memory device may include a plurality of data blocks, a plurality of replacement blocks to replace bad blocks, and a system block configured to store default system information. The memory controller may store, based on a result of comparing a lifetime of the memory device with a reference value, update system information corresponding to an update of the default system information, in a selected replacement block among the plurality of replacement blocks. The memory controller may control the memory device to set the selected replacement block as a target system block. The default system information may include one or more parameters corresponding to at least one operation among a read operation, a program operation, and an erase operation of the memory device.
