Abstract

See full text

A device for storing data in a plurality of multi-level cell memory chips. The device includes a scrambling unit to generate a plurality of candidate scrambled sequences of data by performing a plurality of scrambling operations on a sequence of data to be stored, a calculation unit to calculate a cost function for each of the plurality of candidate scrambled sequences of data, the result of each cost function being indicative of a balancing degree of subsequences of a candidate scrambled sequence, when the subsequences of the candidate scrambled sequence are written to the plurality of multi-level cell memory chips, a selection unit to select one of the candidate scrambled sequences of data based on the results of the cost functions, and a storing unit to store the selected candidate scrambled sequence of data in the multi-level cell memory chips by storing the subsequences across the multi-level memory chips.
