ERROR DETECTION AND CORRECTION FOR EXTERNAL DRAM |
摘要 |
One embodiment of the present invention sets forth a technique for protecting data with an error correction code (ECC). The data is accessed by a processing unit and stored in an external memory, such as dynamic random access memory (DRAM). Application data and related ECC data are advantageously stored in a common page within a common DRAM device. Application data and ECC data are transmitted between the processor and the external common DRAM device over a common set of input/output (I/O) pins. Eliminating I/O pins and DRAM devices conventionally associated with transmitting and storing ECC data advantageously reduces system complexity and cost. |
