DATA STORING IN MEMORY ARRAYS

摘要

Methods and systems for storing data in memory arrays are described. In one implementation, input bits are encoded into an intermediate binary array having multiple sub-arrays iteratively appended row-wise to the intermediate binary array. First sub-array is generated based on the input bits such that each row of the first sub-array has a number of 1's equal to a fraction of number of columns in the first sub-array, and based on a column balance coding such that the columns of the first sub-array have an equal number of 1's. At least one subsequent sub-array is generated based on a set of bits obtained from balancing termination indices for a previous sub-array and from diagonal bits of the intermediate binary array that are a part of the previous appended sub-array. The intermediate binary array is transformed to an encoded bit pattern. The encoded bit pattern is stored in the memory array.
