  • Patent number: 7453285
    Abstract: A dynamically configurable logic gate includes an input summer for receiving a first input signal and a second input signal to generate a summed input signal. Further the dynamically configurable logic gate includes a nonlinear element that applies a nonlinear function to the summed input signal to produce a nonlinear output signal. The dynamically configurable logic gate output signal corresponds to one of a plurality of different logic gates responsive to adjusting the summed input signal and/or the nonlinear function. In another embodiment, the dynamically configurable logic gate includes feedback to one of the inputs. The dynamically configurable logic gate receives the two inputs and operates as one of a plurality of different logic gate types so as to produce an output signal that corresponds to a memory latch according to a selection of the control signal. An array structure of dynamically configurable logic elements is also disclosed.

  • Patent number: 5880989
    Abstract: A method of operating a 1T/1C ferroelectric memory having a memory cell coupled to a word line, a bit line, and a plate line, includes the steps of turning on the word line, energizing the plate line to establish a charge on the bit line, turning off the word line, and sensing the charge on the bit line while the word line is off.
