摘要： The present general inventive concept relates to a solid state drive and a method of controlling an error thereof. A flash translation layer includes a parity managing module to correct errors. A block address of a storage medium including error data that can be recovered is managed through the parity managing module. Parity data of a block including error data is generated through the parity managing module. The generated parity data is managed through the parity managing module. The generated parity data can be stored in an assigned area of the storage medium. When data of a block managed by the parity managing module is not recovered by an error correction code unit, error data is recovered with reference to the generated parity data.

摘要： A data mapping method is performed by a memory controller in a data storage system configured to control a nonvolatile memory device having a plurality of channels, where each channel includes a plurality of nonvolatile memories. The data mapping method includes selecting channels of the plurality of channels to be active channels to which data input from a host are written in response to a request from the host, including nonvolatile memories corresponding to each of the active channels in a candidate zone list as active zones, and sequentially writing the data input from the host to the active zones included in the candidate zone list.

摘要： A non-volatile memory controller, system and method capable of processing a next request as an interrupt before completing a current operation are disclosed. The non-volatile memory system includes a first memory storing meta data loaded from a flash memory; a second memory storing the meta data copied from the first memory; and a flash memory controller copying the meta data from the first memory to the second memory, changing the meta data in the second memory, and then re-copying the changed meta data from the second memory to the first memory during a first-type operation that requires changes in the meta data.
