Abstract: A memory controller replaces a bad block of a given super block with a reserved block, and updates a bad block bitmap. The memory controller includes a super block classifier configured to determine the given super block as a free block or a reserved block according to a number of bad blocks of the given super block. When the given super block is determined as the free block, memory controller inserts an identifier of the given super block into a free block list.

Abstract: A brush apparatus includes a core portion rotating around a length direction as an axis, a main body portion at least partially surrounding the core portion, a plurality of protrusion portions protruding from the main body portion, and a detection portion disposed in at least a part of the main body portion and the plurality of protrusion portions. The detection portion is formed of poly vinyl acetal (PVA) including detection components that react with ceria.
