Abstract
Methods, systems and computer program products for providing access to a spare memory array element ('MAE') are provided. Aspects include storing a row number a column number associated with a defective MAE of a plurality of MAEs. The plurality of MAEs are logically arranged in a plurality of rows and a plurality of columns. Aspects also include receiving a command to access a cache line. The cache line corresponds to a selected row of MAEs of the plurality of MAEs. Responsive to determining that the selected row matches the row number that is associated with the defective MAE, aspects include activating one or more column shifters to prevent access to the defective MAE and provide access to a spare MAE when accessing the cache line. The activation of the one of more column shifters is based on the column number that is associated with the defective MAE.
