Reliable and secure memories based on algebraic manipulation correction codes
Zhen Wang, Mark G. Karpovsky · 2012
The reliability and security of memories are crucial considerations in the modern digital system design. Traditional codes usually concentrate on detecting and correcting errors of certain types, e.g. errors with small multiplicities or byte errors, and cannot detect or correct unanticipated errors. In this paper we present a reliable and secure memory architecture based on robust Algebraic Manipulation Correction codes. These codes can provide a guaranteed error detection probability and can correct any error regardless of its multiplicity as long as the error stays for several consecutive clock cycles. The construction and the error correction procedure for the code will be described. The probability that an error can be successfully detected and/or corrected and the hardware overhead of the memory architecture based on these codes will be estimated.
