ABSTRACT:
According to the present invention, a memory system comprises storing section having a plurality of memory elements each of which stores one of n-value storage states corresponding to data "0", "1", . . . , "n-1", and including a plurality of information memory elements for storing n-value information data and a plurality of check memory elements for storing check data, converting section for respectively converting the information data and the check data stored in the memory elements into binary codes having a plurality of bits each constituted by 0 or 1, the binary codes corresponding to the information data and the check data, and detecting/correcting section for detecting and correcting an error on the basis of the binary codes corresponding to the check data and the information data.
