Abstract
FIFO memory devices include a multi-port cache memory device configured to generate a data word along with a plurality of diagnostic bits. These diagnostics bits encode an error correction status of the data word and a path traversal status of the data word through the FIFO memory device. In particular, the diagnostic bits identify all cases of whether the data word includes a corrected or uncorrected error, is without error or is unchecked for errors because the data word did not pass through error detection and correction circuitry within the FIFO memory device.
