Abstract:
A storage device and a method for operating the storage device are provided. A storage device includes processing circuitry configured to write multi-stream data on a non-volatile memory; generate parity data of the multi-stream data and/or intermediate parity data upon which the parity data is based; store the parity data and/or the intermediate parity data in a first memory; and perform a data swap between the first memory and a second memory, wherein a number of slots of a plurality of slots in the first memory is based on a number of execution units of program buffering of the non-volatile memory.
Abstract:
A method of demodulating a modified dual carrier modulation (MDCM) signal using hard decision includes generating real symbol vector candidates and imaginary symbol vector candidates which correspond to an MDCM signal pair; calculating a first norm between a real part of the MDCM signal pair and each of the real symbol vector candidates and determining as a real symbol vector a real symbol vector candidate that has the minimum first norm among the real symbol vector candidates; and calculating a second norm between an imaginary part of the MDCM signal pair and each of the imaginary symbol vector candidates and determining as an imaginary symbol vector an imaginary symbol vector candidate that has the minimum second norm among the imaginary symbol vector candidates.
Abstract:
A storage controller and an operating method of the storage controller are provided. The storage controller includes processing circuitry configured to read sub-stripe data from each of a plurality of non-volatile memory devices connected with a RAID (Redundant Array of Inexpensive Disk), check error information of at least one of the sub-stripe data, and perform a RAID recovery operation in response to the at least one of the sub-stripe data having an uncorrectable error, and a RAID memory which stores calculation results of the RAID recovery operation.

Abstract:
A data storage device is provided. The data storage device includes a storage medium configured to store data blocks included in a stripe set, and a controller connected to the storage medium and configured to, decode a first data block disposed in a column among the data blocks, during a read operation of the first data block, and read first group data blocks disposed in the column among the data blocks, based on a read failure of the first data block.
