Abstract
The invention relates to a multi-level storage device including: at least a first plurality of cells storing an identical first number (greater than one) of binary data, and at least a corresponding for second plurality of cells for storing a second number of error check and correcting words equal to said first number, said words being respectively associated with sets of binary data, each including at least one binary data for each cell in said first plurality. In this way, many of the known error correction algorithms can be applied to obtain comparable results to those provided by binary memories. In addition, where multi-level cells are used for storing the error check and correcting words, the device dimension requirements can also be comparable.
