An apparatus is provided that comprises a processor. The processor comprises a cache to store data, a decoder, an error classification module, and an error correction module. The cache stores data, the data encoded as a codeword. The decoder reads the codeword from cache and calculates a syndrome of the codeword using an H-matrix. The error classification module determines an error type of the syndrome. The H-matrix is redesigned such that the columns form a geometrical sequence, and as a result not only the t-bit random errors but also (t+1) bit adjacent errors can be corrected. The error correction module, triggered by the enhanced error classification module, takes one of two sets of inputs depends on the error type (either random or adjacent error) and produces corrected data from the syndrome when the syndrome comprises a detectable and correctable error.
