Abstract

A data erase operation is performed on the memory system. The directed data erase operation performed on the memory system erases blocks of the memory device including blocks that are indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as valid without erasing those groups of memory cells (e.g., blocks) indicated as invalid. In some embodiments, a data erase operation that can be performed on a memory system may obtain information associated with failing scenes of groups of memory cells (e.g., blocks) prior to obtaining the information, and erase the blocks (e.g., invalid blocks) subsequently.
