Abstract
Techniques and mechanisms for supporting error correction of data accessed in a non-volatile (NVM) memory. In an embodiment, a memory controller performs reads each of the same codeword from the NVM, wherein a first read is based on a first reference voltage, and a second read is based on a second reference voltage. Based on the first read and the second read, confidence values are assigned each to respective bits of the codeword. Error correction comprises applying a weights to respective bits of the codeword based on the confidence values. In other embodiments, a relatively low confidence value is assigned to codeword bits that have a different value for the first read and the second read.
