Abstract
An apparatus, system, and method are disclosed for distinguishing correctable bit errors in memory. A bit error detection module detects a correctable bit error in memory. The correctable bit error is correctable using error-correcting code ('ECC'). A comparison module compares an error location indicator with a stored error location indicator. The error location indicator is a location of the correctable bit error. The stored error location indicator includes to at least one previously stored error location indicator of a previously detected correctable bit error. A storage module stores the error location indicator in response to the comparison module determining that the error location indicator differs from a stored error location indicator. A bit error counter module increases a random bit error counter if the comparison module determines that the error location indicator differs from a stored error location indicator and does not increase the random bit error counter otherwise.
