Grown bad block management in a memory sub-system

Abstract:

A replacement block pool for a memory device is established. The replacement block pool comprises one or more valid blocks from a set of valid blocks in the memory device determined based on a constraint defining a minimum number of valid blocks for the memory device. A grown bad block is detected in the memory device. The grown bad block is replaced with a replacement block from the replacement block pool in response to detecting the grown bad block.
