Content
A BES read scan operation, in one embodiment, may determine an estimated bit error rate by comparing syndrome weights between iterative read level sensing or read operations to determine which candidate read level results in the fewest number of activated memory cells. In such embodiments, a syndrome weight below a threshold serves as a proxy for a bit error rate, an estimated bit error rate. A syndrome weight is a number of unsatisfied ECC parity check equations nodes/equations from a Low-Density Parity-Check (LDPC) error correction code decoder (ECC decoder).
