Abstract
Error correction in a memory subsystem includes determining whether an error is a transient error or a persistent error, and adjusting an approach to ECC (error checking and correction) based on error type. The type of error can be determined by a built in self-test. If the error is a persistent error, the memory controller can perform in erasure mode, including correcting an erasure for an identified error location prior to applying an ECC correction algorithm. Otherwise, if the error is transient, the memory controller can perform standard full ECC correction by applying the ECC correction algorithm.
