Energy efficient storage of error-correction-detection information

Abstract:

Data and error correction information may involve accessing multiple data channels (e.g., 8) and one error detection and correction channel concurrently. This technique requires a total of N+1 row requests for each access, where N is the number of data channels (e.g., 8 data row accesses and 1 error detection and correction row access equals 9 row accesses.) A single (or at least less than N) data channel row may be accessed concurrently with a single error detection and correction row. This reduces the number of row requests to two (2)--one for the data and one for the error detection and correction information. Because, row requests consume power, reducing the number of row requests is more power efficient.
