Abstract
Embodiments provide crossbar structures, and reconfigurable circuits that contain crossbar structures, that include n inputs and an output, where n is an integer, chains of transistors coupled to the n inputs and the output, a plurality of control signal elements—each coupled to one or more transistors of the plurality of chains of transistors to selectively couple said n inputs to the output—and an additional chain of transistors coupled to at least some of the plurality of control signal elements and the output to selectively couple a constant output voltage to the output. Other embodiments may be disclosed and claimed.
Claims26
A crossbar structure comprising:
- n inputs and an output, where n is an integer;
- a plurality of chains of transistors coupled to the n inputs and to the output;
- a plurality of control signal elements, each coupled to one or more transistors of the plurality of chains of transistors to selectively couple said n inputs to the output;
- and
- an additional chain of transistors coupled to at least some of the plurality of control signal elements and to the output to selectively couple a constant output voltage to the output.
A reconfigurable circuit comprising:
- a plurality of crossbar devices coupled to one another, at least one of the crossbar devices having:
- n inputs and an output, where n is an integer;
- a plurality of chains of transistors coupled to the n inputs and to the output;
- a plurality of control signal elements, each coupled to one or more transistors of the plurality of chains of transistors to selectively couple said n inputs to the output;
- and
- an additional chain of transistors coupled to at least some of the plurality of control signal elements and the output to selectively couple a constant output voltage to the output.
A crossbar structure comprising:
- n inputs and at least one output, where n is an integer;
- a plurality of chains of logic elements coupled to the n inputs and to the at least one output;
- a plurality of control signal elements, each coupled to one or more of the plurality of chains of logic elements to selectively couple said n inputs to the output;
- and
- a switching circuit coupled to at least one of the plurality of control signal elements, the plurality of chains of logic elements, and the at least one output to divide the plurality of chains of logic elements into a first subset of chains of logic elements and a second subset of chains of logic elements.
