Abstract:
A programmable output driver circuit, comprising:a control signal generator that generates a first control signal on a first control signal line and a second control signal on a second control signal line, in response to a mode control signal and an address;a first pull-up/pull-down driver circuit, said first pull-up/pull-down driver circuit having a data input, a control signal input responsive to the first control signal and an output;a second pull-up/pull-down driver circuit, said second pull-up/pull-down driver circuit having a data input electrically coupled to the data input of said first pull-up/pull-down driver circuit, a control signal input responsive to the second control signal and an output electrically coupled to the output of said first pull-up/pull-down driver circuit; anda mode register set controller that generates the mode control signal in response to a plurality of command signals;wherein said control signal generator comprises a plurality of devices having first inputs that receive the mode control signal and second inputs that receive the address, wherein said control signal generator also generates complementary versions of the first and second control signals; wherein said first pull-up/pull-down driver circuit is responsive to the complementary version of the first control signal; and wherein said second pull-up/pull-down driver circuit is responsive to the complementary version of the second control signal.
