1. A method, comprising:
selecting a first block comprising a first set of memory cells based at least in part on determining that a second block is unreliable for storing information, wherein each memory cell of the first set of memory cells is configured for storing a first quantity of one or more bits;
configuring each memory cell of the first set of memory cells in the first block for storing a second quantity of bits that is more than the first quantity of one or more bits based at least in part on determining that the second block is unreliable;
determining, based at least in part on configuring the first set of memory cells for storing the second quantity of bits, a remaining quantity of access operations permitted to be performed on the first block, wherein the remaining quantity of access operations for the first block is based at least in part on a ratio between a first threshold quantity of access operations associated with the first block and a second threshold quantity of access operations associated with the second block; and
operating the first block based at least in part on the remaining quantity of access operations for the first block.
