Title: METHOD AND DATA STORAGE DEVICE TO ESTIMATE A NUMBER OF ERRORS USING A CONVOLUTIONAL LOW-DENSITY PARITY-CHECK (LDPC) CODE
Abstract:
In an illustrative example, a method includes sensing at least a portion of a representation of a convolutional low-density parity-check (CLDPC) codeword stored at a memory of a data storage device. The method further includes receiving the portion of the representation of the CLDPC codeword at a controller of the data storage device. The method further includes performing one or more management operations associated with the memory based on an estimated number of errors of the portion of the representation of the CLDPC codeword.
