Abstract
A data storage system configured to adaptively code data and related methods are disclosed. In some embodiments of the present invention, a data storage system includes a controller and a non-volatile memory array having a plurality of memory pages. The controller includes a channel monitor that determines the quality of read signals from the pages when they are read, and provides adjustment metrics to aid in the selection of a code rate, such as a code rate for a low-density parity-check (LDPC) code. In this way, the code rate used for data encoding can be dynamically adjusted to accommodate degradation of the non-volatile memory array over its useable life.
