Abstract
A Multi Level Cell (MLC) nonvolatile memory is tested and, if it fails to meet an MLC specification, is reconfigured for operation as an SLC memory by assigning two of the MLC memory cell states as SLC states in a first SLC mode, according to predefined sets of criteria. Subsequently, different MLC memory cell states are assigned as SLC states in a second SLC mode.
