Determining hard errors vs. soft errors in memory

摘要

In a preferred embodiment, the invention provides a method for determining soft and hard errors in memory. First one or more errors are detected in memory. Next correct data is written back to the memory locations were the error(s) were detected. Data is then read from the memory locations where the correct data was written. If the data that was read is correct, the memory locations where error(s) were detected are written to a register block indicating a soft error. If the data that was read is not correct, the memory locations where error(s) were detected are written to a register block indicating a hard error.
