Abstract: A memory circuit includes a bond option circuit 106 having an input and an output, and row control circuitry 100 coupled to the output of the bond option circuit, the row control circuitry including address terminals, A12 and A13. The memory circuit also includes column control circuitry 102 coupled to the output of the bond option circuit, the column control circuitry 102 also including address terminals, A12 and A13. A memory cell array is coupled to the row control and column control circuitry and is arranged in a first plurality of banks of memory cells, the banks being selectable by a combination of address signals on the address terminals of the row control and column control circuitry. In response to a first signal at the input of the bond option circuit 106, the bond option circuit produces a second signal at the output of the bond option circuit that is coupled to the row control 100 and column control 102 circuitry.
