Abstract
The present invention provides a method of operating a memory device storing error correcting codes ECCs for corresponding data and including ECC logic to correct errors using the ECCs. The method includes correcting data using ECCs for the data on the memory device, and producing information on the memory device about the use of the ECCs. The method provides the ECC information on an output port of the device in response to a command received on an input port from a process external to the memory device. The present invention also provides a method of controlling a memory device. The method includes sending a command to the memory device requesting ECC information corresponding to data in the memory device, and receiving the ECC information from the memory device in response to the command. The method includes performing a memory management function using the ECC information.
