摘要:
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.

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.

摘要:
A non-volatile memory device including a memory unit configured to store user data and metadata and a memory controller unit. The memory controller unit is configured to access the memory unit in response to a request from an external host, create metadata which is to be recorded in the memory unit, and convert a format of the metadata based on a result of counting the number of times the memory unit is accessed.
摘要:
Provided are an apparatus for collecting garbage blocks of a nonvolatile memory according to a power state and a method of collecting the same, and more particularly, an apparatus for collecting garbage blocks of a nonvolatile memory according to a power state and a method of collecting the same, in which an amount of power consumed by a portable device can be reduced by adjusting a garbage block collection operation on the basis of the power state of the portable device. The apparatus includes a power managing unit which collects physical blocks allocated to the nonvolatile memory on the basis of the power state of a portable device.
