Abstract
Systems and methods are disclosed for decoding solid-state memory cells using one-read soft decision decoding. A controller of a data storage device is configured to perform a first decoding of a first code word based at least in part on data associated with a reading of the first code word, and to detect a decoding failure associated with the first decoding. The controller determines reliability information for decoding the first code word in response to the decoding failure based at least in part on data associated with a successful decoding of a second code word and performs a second decoding of the first code word based at least in part on the reliability information.
