Early detection of compression status using inline metadata
Abstract:
Disclosed in some examples are methods, systems, memory devices, and machine-readable mediums which store a single compressed value per line with a marker value in a front of the compressed version of the memory line. In some examples, the only value stored in the memory line is the value normally stored therein. This removes the complexity of the prediction tables and the inclusion of invalid values as well as preventing the penalty when those prediction tables are wrong. Furthermore, by inclusion of the marker in the beginning of the memory line, the system can quickly determine the compression status of the memory line without having to read the entire line. That is, it can quickly stop reading the rest of the memory line once the compressed data is read out which saves the memory device from having to read the entire line.
