Abstract: A storage device may include a non-volatile memory including a plurality of zones, the non-volatile memory configured to sequentially store data in at least one of the plurality of zones, and a processing circuitry configured to, receive a first write command and first data from a host, the first write command including a first logical address, identify a first zone of the plurality of zones based on the first logical address, compress the first data based on compression settings corresponding to the first zone, and write the compressed first data to the first zone.

Abstract: Disclosed is a method for programming a storage device including a nonvolatile memory device and a storage controller for storing multi-bit data, programming, by the storage controller, the multi-bit data into the nonvolatile memory device based on a pre-programming operation, reading state group data of the multi-bit data generated in the nonvolatile memory device based on a program result of the pre-programming operation, and performing, by the storage controller, error correction decoding on the state group data.

Abstract: A memory controller receives a write request and write data from a host, stores first entry information including a write buffer pointer indicating a location where the write data is temporarily stored in a write buffer and a first logical address corresponding to the write request in an entry buffer, stores an entry index generated based on the first entry information in a first storage space corresponding to the first logical address in a logical-to-physical (L2P) mapping information storage circuit, and updates the entry index stored in the first storage space to a physical address newly mapped to the first logical address as the write data is programmed in a memory device.
