Abstract
A method includes directing an access of a memory location of a memory device to an error correction code (ECC) decoder in response to receiving a test activation request indicating the memory location. The method also includes writing a test pattern to the memory location and reading a value from the memory location. The method further includes determining whether a fault is detected at the memory location based on a comparison of the test pattern and the value.
