Majority detection in error recovery

Abstract

One or more techniques provide majority detection in error recovery. Accordingly, a device retries reading an ECC codeword having one or more bits for a plurality of retries, and stores each retry. The device (“hard” majority detection) votes on a value of each bit of the codeword based on a majority of corresponding retry values in the plurality of corresponding retries. Also, the device (“soft” majority detection) may determine reliability information for a value of each bit of the codeword based on a reoccurrence ratio of corresponding retry values in the plurality of retries. The device may declare erasures based on the reliability information and a (dynamically adjusted) threshold of uncertainty, e.g., where an “uncertain” bit based on the threshold or any symbol with an “uncertain” bit is declared as an erasure.
