| 1. A method of providing a read signal to a memory cell, comprising:
receiving an address on row address lines ranging from a most significant bit row address line to a least significant bit
row address line;
coupling a fixed high logic input to a first input of a row driver logic device associated with a local out of range address;
and
providing logic to send a read enable signal on a bit line coupled to an output of the row driver logic device coupled to
the memory cell if the address is the local out of range address;
wherein the memory cell has a three bit address and wherein the row driver logic device is associated with the local out of
range address if the out of range address has the same two least significant bit values as the two least significant bits
of the address of the memory cell.
