Memory system and related error detection and correction apparatus wherein the memory, independently on its parallelism, is organized in modules having single byte parallelism, each module having a section with a plurality of bit parallelism for storing SEC-DED codes related to the information stored in the module and wherein a fast memory, addressed with the information codes and the related SEC-DED codes read out from a memory module produces an information output code, corrected as a function of the SEC-DED code, a parity check bit for the corrected information code, and further bits indicative of a corrected single error and a multiple error which cannot be corrected.
