1. A nonvolatile memory, comprising: (A) a configuration cell that stores a first configuration signal; (B) a configuration register that stores a second configuration signal that can be at one of a first and a second state; (C) a logic gate coupled to the configuration cell and the configuration register; and (D) a multiplexer that selectively couples an output of one of (1) the configuration register and (2) the logic gate to a control circuit of the nonvolatile memory, wherein when the multiplexer couples the output of the configuration register to the control circuitry, the nonvolatile memory is configured by the second configuration signal, wherein when the multiplexer couples the output of the logic gate to the control circuit and the second configuration signal is at the first state, the logic gate passes the first configuration signal to the control circuit to configure the nonvolatile memory, wherein when the multiplexer couples the output of the logic gate to the control circuit and the second configuration signal is at the second state, the logic gate alters the first configuration signal without reprogramming the configuration cell and passes an altered first configuration signal to the control circuit to configure the nonvolatile memory, wherein the configuration cell, the configuration register, the logic gate, and the multiplexer all reside on the same chip as the memory.
