Abstract
Information stored as physical states of cells of a memory is read first by setting each of one or more references to a respective member of a first set of values and reading the physical states of the cells relative to the values of the first set. Subsequently, the references are set to respective members of a second set of values, and the physical states of the cells are read again relative to the values of the second set. The second set is different from the first set, so that the two readings together read the physical states of the cells with higher resolution than the first reading alone.
