Abstract
A data storage apparatus includes a nonvolatile memory device, a processor configured to control operation of the nonvolatile memory device, and a memory loaded with a flash translation layer (FTL) including modules, the memory including a map cache buffer configured to cache at least one map segment. The modules include a map module configured to manage a map cache data structure related to the map cache buffer and a map cache allocation module configured to receive, from a module other than the map module, an allocation request for an allocating region having a required size in the map cache buffer; provide the allocation request to the map module; receive allocable size information from the map module; and provide the allocable size information to the module.
