摘要:
A data processing device 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.

A method of programming multi-level cells included in a spare region, the method including programming first page data and at least one first dummy data in a first multi-level cell; and programming second page data and at least one second dummy data in a second multi-level cell.
摘要:
A storage device includes a controller unit and a memory cell array. The controller unit is for outputting data through a first data path or a second data path according to a property of externally supplied input data. The memory cell array includes a first memory and a second memory, and receives and stores the data from the controller unit output through the first and second data paths. The first memory has a different memory cell structure than the second memory.
摘要:
A method setting a read voltage to minimize data read errors in a semiconductor memory device including multi-bit memory cells. In the method, a read voltage associated with a minimal number of read data error is set based on a statistic value of a voltage distribution corresponding to each one of a plurality of voltage states.

摘要:
An apparatus and a method for reading from a non-volatile memory whereby soft decision data is used to determine the reliability of hard decision data. The hard decision data read from the non-volatile memory is de-randomized and the soft decision data read from the non-volatile memory is not de-randomized. Using the soft decision data, the hard decision data is decoded.
