[PATCH v6 0/5] Micron SLC NAND filling block

2020-05-25 Thread Bean Huo
From: Bean Huo Hi, On planar 2D Micron NAND devices when a block erase command is issued, occasionally even though a block erase operation completes and returns a pass status, the flash block may not be completely erased. Subsequent operations to this block on very rare cases can result in
