Abstract
A memory device is disclosed that includes a row of storage locations that form plural columns. The plural columns include data columns to store data and a tag column to store tag information associated with error locations in the data columns. Each data column is associated with an error correction location including an error code bit location. Logic retrieves and stores the tag information associated with the row in response to activation of the row. A bit error in an accessed data column is repaired by a spare bit location based on the tag information.
