Systems, methods and computer program products for providing a nested two-bit symbol bus error correcting code. Methods include constructing a nested error correcting code (ECC) scheme. The method includes receiving a Hamming distance n code. A symbol correcting code H-matrix is created by iteratively adding rows of H-matrix bits on a symbol column basis such that the symbol correcting code H-matrix describes a symbol correcting code, and the Hamming distance n code is preserved as a subset of the symbol correcting code H-matrix.
