A new version of Self-Adjusting Output Data Compression is put forward as a method of multiple-error detection in RAM. The parity-check matrix of a linear code with suitably large code distance is used to compress RAM content. The matrix columns are essentially generated in real time from memory addresses. The reliability of the method is determined by the code distance of the parity-check matrix used for compression. A hardware realization of the method is proposed.
