A memory integrated circuit device is provided. The device includes a plurality of regular address inputs and at least one spare address input configured for a selected mode or an unselected mode. The device includes a plurality of control inputs, a plurality of data inputs, and a plurality of data outputs. The device has a plurality of memory arrays. Each of the memory arrays comprises a plurality of memory cells. Each of the plurality of memory cells is coupled to a data input/output. The device has a spare group of memory cells comprising a plurality of spare memory cells. Each of the plurality of spare memory cells is externally (or internally) addressable using the address match table and configured with the spare address input; whereupon the spare address input is coupled to the address match table to access the spare memory cells. |
