Abstract
According to the present technology, a storage device may include a plurality of first memory devices, a second memory device, and a memory controller. Each of the plurality of first memory devices may include a plurality of zones in which sequential writing is performed. The second memory device may include a plurality of parity zones. The memory controller may allocate to a parity group, first zones included in the respective first memory devices and a first parity zone storing parity data for data stored in the first zones, release from the parity group, the first zone invalidated among the first zones by writing new data into a target zone different from the invalidated first zone among the zones included in the first memory device including the invalidated first zone, and allocate the target zone to the parity group.
