US 11,145,389 B2 · Detection and error-handling of high error rate blocks during copyback

Abstract

An embodiment of an electronic apparatus may include one or more substrates, and logic coupled to the one or more substrates, the logic to control a persistent storage media including a first media to store one or more source blocks of data and a second media to store one or more destination blocks of data, determine if an error rate associated with a read of a particular destination block of the one or more destination blocks exceeds a threshold error rate, identify a particular source block of the one or more source blocks which corresponds to erroneous data in the particular destination block, determine which of the particular source block and the particular destination block is a failed block, and retire the failed block. Other embodiments are disclosed and claimed.
