Abstract
A memory has a programmable circuit which allows a user to select an amount of redundancy the memory has varying from zero percent to one-hundred percent. A received address is compared by the circuit with a redundancy percentage control signal to determine if the address falls within a redundant portion of the memory. If so, a redundancy enable signal is asserted to allow the memory to utilize the redundant circuitry.
