Abstract
A data storage device includes: a non-volatile memory device, a random access memory and a processor. The non-volatile memory device stores a plurality of L2P entries related to a plurality of logical addresses. The random access memory stores a sequential flag table including sequential flags for a plurality of sequential segments. Each of the sequential flags are flags representing whether physical addresses corresponding to the logical addresses of the sequential segments are sequential or not. The processor identifies a sequential flag of a sequential segment related to read logical address information based on the sequential flag table. The processor reads at least one of the L2P entries, which are correspond to the read logical address information based on the sequential flag and loads the read L2P entry into the random access memory.
