Abstract
A method and apparatus for identifying data that contains an uncorrectable error may be accomplished in a computer that includes a memory unit operably coupled to a processor. The memory unit includes an error detection circuit that, when an uncorrectable storage error is detected, produces transmit check bits indicating that the data being transmitted includes an uncorrectable storage error. The processor, which includes a check bit decoder, upon receiving the transmit check bits, interprets the transmit check bits to identify the uncorrectable error. When the uncorrectable error is identified, the check bit decoder provides a data error signal to a processing core of the processor, thereby interrupting the processing core which avoids a system error and the need to reboot the computer.
