Abstract:
A semiconductor device, comprising:operational circuitry capable of operation in at least two different operating modes; at least two one-time programmable devices each programmable from a first state to a second state; control circuitry, coupled to said at least two one-time programmable devices and to said operational circuitry, said control circuitry being responsive to a first combination of states of said at least two one-time programmable devices to control said operational circuitry to operate in a first of said at least two operating modes; said control circuitry being further responsive to a second combination of states of said at least two one-time programmable devices to control said operational circuitry to operate in a second of said at least two operating modes; and said control circuitry being further responsive to a third combination of states of said operational circuitry to control said operational circuitry to operate in said first of said at least two operating modes.
