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.
