Bitline deletion

A method for bitline deletion, the method comprising:

• detecting a first error when reading a first cache line in an array within a cache;
• recording a first bitline address and a first wordline address of the first error in the first cache line;
• detecting a second error when reading a second cache line in the array within the cache;
• recording a second bitline address and a second wordline address of the second error in the second cache line;
• comparing the first bitline address to the second bitline address;
• comparing the first wordline address to the second wordline address;
• activating, by a cache controller, a bitline delete mode based on the first bitline address matching the second bitline address and the first wordline address not matching the second wordline address;
• detecting a third error when reading a third cache line in the array within the cache;
• recording a third bitline address of the third error in the third cache line;
• comparing the second bitline address to the third bitline address of the third cache line;
• and
• removing, by the cache controller, a location corresponding to the third cache line from available cache locations based on the bitline delete mode being activated and the third bitline address matching the second bitline address.
