    摘要: A memory device and a method of operating a memory device is disclosed. In one embodiment of the invention, the memory device includes a plurality of multi-level memory cells each having a number m of levels not matching 2n with n being a non-zero integer, and a circuit or device for combining the levels of at least two of the memory cells for write and read operations into a set of combined states and for transforming at least a subset of 2n combinations of the set of combined states into n two-level data bits.
