Abstract
This application is directed to compressing check node data for an electronic device. The electronic device identifies a check node corresponding to a subset of codeword symbols in a block of data and determines check node data that indicates a likelihood of the subset of codeword symbols being erroneous. A set of data bits are determined based on a value combination of data items of the check node data to uniquely identify the value combination among a set of selected value combinations according to a predefined relationship. The electronic device stores, in a memory block, the set of data bits representing the data items of the check node data of the check node. Each data item requires more data bits to represent all possible values of the respective data item than data bits of the set of data bits.
