Abstract
A memory apparatus includes memory cells configured to retain a threshold voltage corresponding to data states. The memory cells are grouped into blocks and operable as one of single-level cells storing one bit of data per each of the memory cells or multi-level cells storing a plurality of bits of the data per each of the memory cells. A control means is configured to determine whether the memory cells of one of the blocks were previously used as the multi-level cells. The control means is also configured to determine the memory cells of the one of the blocks should be used as the multi-level cells only in response to determining the memory cells of one of the blocks were previously used as the multi-level cells and an occurrence of at least one failure to decode the data of the memory cells of the one of the blocks.
