1. A memory bank comprising:
memory cells; and at least one additional cell configured to determine an operating voltage of the memory bank, the at least one additional cell being configured such that at least one operating margin of the at least one additional cell is less than a corresponding operating margin of the memory cells, wherein an operating voltage of the memory bank is determined based on failure of the at least one additional cell.
