Embodiments relate to a method including detecting a first error when reading a first cache line, recording a first address of the first error, detecting a second error when reading a second cache line and recording a second address of the second error. Embodiments also include comparing the first and second bitline address, comparing the first and second wordline address, activating a bitline delete mode based on matching first and second bitline addresses and not matching the first and second wordline addresses, detecting a third error when reading a third cache line, recording a third bitline address of the third error, comparing the second bitline address to a third bitline address and deleting a location corresponding to the third cache line from available cache locations based on the activated bitline delete mode and the third bitline address matching the second bitline address.
