US Patent 11182246 Continuous error coding

Systems, methods, and circuitries are disclosed for protecting data throughout read and write operations. In one example a method includes receiving a plurality of data bits; dividing the plurality of data bits into at least two data blocks; generating respective sets of block check bits for each respective data block using a respective first error code; combining the sets of block check bits to generate a set of signature bits for the plurality of data bits; generating a set of cumulative check bits for the plurality of data bits and the set of signature bits using a second error code; and storing, in a memory location, the plurality of data bits, the set of signature bits, and the set of cumulative check bits.
