摘要:
A storage device includes a nonvolatile memory device including a plurality of memory cells, the memory cells divided into a plurality of pages, and a controller configured to control the nonvolatile memory device. The storage device is configured to collect two or more write data groups to be written to two or more pages, to simultaneously perform a common write operation with the two or more pages based on the two or more write data groups, and to sequentially perform an individual write operation with each of the two or more pages based on the two or more write data groups.
摘要:
A method is provided for operating a data storage device capable of compensating for an initial threshold voltage shift of multiple memory cells. The method includes generating a first compression value for a first write address corresponding to a first write request input during a first time interval among different time intervals, and storing the first compression value in a first table among multiple tables.
摘要:
A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.
摘要:
A data processing which includes a conversion circuit and a pseudo random number generator including a series connection of plural shift registers. The conversion circuit receives a pseudo random number sequence from an output of one of the plural shift registers excluding a last shift register of the series connection, and converts first data to second data using the received pseudo random number sequence.
