Abstract
Methods, systems, and devices for sacrificial block pool are described. For instance, a memory device may allocate a first pool of blocks and a second pool of blocks. The first pool of blocks may be associated with access operations in which each memory cell stores a single bit and the second pool of blocks may be associated with operations where each memory cell stores a single bit or multiple bits. The memory device may perform access operations according to the allocation, where for the access operations a first wear-leveling criteria is applied to a first subset of the second pool of blocks and a second wear-leveling criteria is applied to a second subset of the second pool of blocks. The memory device may move a block of the second subset to the first pool of blocks based on an amount of access operations associated with the block satisfying a threshold.
