Computer system operation with corrected read data function

A computer system comprising:

• a) a CPU and a memory, the CPU having means for sending data items to the memory for storing identified by physical addresses and for sending requests to said memory to read selected ones of said data items;
• b) the memory having ECC means for storing said data items along with an ECC code for each item and retrieving said data items and checking said data items against said ECC code to detect and correct any correctable errors occurring;
• c) said memory having means for sending to said CPU an identification print of said physical address in memory of each said data item for which said correctable error is detected and corrected;
• d) said CPU having means for storing said identification prints and comparing each one of said identification prints representing a correctable error, before storing, with previously-stored ones of said stored identification prints to see if a match exists;
• e) means for scrubbing a location in said memory containing each said physical address for which a correctable error was detected;
• and
• f) means for moving each page of said memory to another page location in said memory when a correctable error occurs having an identification print matching that of a previous correctable error.

A method of operating a computer system comprising the steps of:

• a) sending data items to memory by a CPU identified by physical addresses;
• b) storing said data items in memory along with an ECC code for each item;
• c) sending requests by said CPU to said memory to read selected ones of said data items;
• d) retrieving said selected ones of said data item from said memory and checking said data items using said ECC code, and correcting each of said data items if a correctable error is detected;
• e) storing by said CPU an identification print of said physical address in memory of each said data item for which said correctable error is detected and corrected;
• f) comparing each one of said identification prints representing a correctable error, before storing, with previously-stored ones of said stored identification prints to see if a match exists;
• e) scrubbing a location in said memory containing each said physical address for which a correctable error was detected;
• and
• f) moving a block of said memory containing the physical address of a correctable error to another location in said memory when a correctable error occurs having an identification print matching that of a previous correctable error.
