A nonvolatile-memory-management includes a generation unit that generates a free block list by arranging an entry including representative information of a group, of which free blocks adjacent to each other are grouped according to predetermined criteria, according to key values where the representative information are combined, a determination unit that determines parameters according to characteristics of data to be recorded, and a block-allocating unit that allocates free blocks satisfying the parameters as an area to be recorded with the data by referring to the free block list.

Apparatus and method for managing nonvolatile memory

Provided are a storage apparatus using a non-volatile memory as a cache and a method of operating the same, in which the non-volatile memory is used as the cache so as to preserve data even when electricity is interrupted. The storage apparatus using a non-volatile memory as a cache includes a main storage medium, the non-volatile memory being used as the cache of the main storage medium and having a stationary region and a non-stationary region divided according to whether data are fixed, and a block management unit managing blocks allocated in the non-volatile memory.

Storage apparatus and method for using a non-volatile cache memory organized into stationary and non-stationary circular regions

A storage apparatus using a nonvolatile memory as a cache and a mapping information recovering method for the storage apparatus are provided. The storage apparatus includes a mapping information storage module which stores in the nonvolatile memory mapping information of the nonvolatile memory and a first physical block address allocated when the mapping information is stored; a scan module which scans the first physical block address through a second physical block address allocated currently; and a mapping information recovery module which recovers the mapping information between the first physical block address and the second physical block address based on a result of the scan by the scan module.
