Patent number: 11863183Abstract: A new class of multiplier cells (analog or digital) is derived from a 1-bit full adder and an AND gate. The 1-bit full adder is derived from first and second majority gates. The multiplier cell can also be implemented with a combination of two majority gates with majority and AND functions integrated in each of them. The two majority gates are coupled. Each of the first and second majority logic gates comprise a capacitor with non-linear polar material. The first and second majority gates receive the two inputs A and B that are to be multiplied. Other inputs received by the first and second majority gates are carry-in input, a sum-in input, and a bias voltage. The bias voltage is a negative voltage, which produces an integrated AND function in conjunction with a majority function. The second majority gate receives additional inputs, which are inverted output of the first majority gate.Type: GrantFiled: October 15, 2021Date of Patent: January 2, 2024Assignee: KEPLER COMPUTING INC.Inventors: Sasikanth Manipatruni, Yuan-Sheng Fang, Robert Menezes, Rajeev Kumar Dokania, Gaurav Thareja, Ramamoorthy Ramesh, Amrita Mathuriya

Publication number: 20230308102Abstract: An adder with first and second majority gates. For a 1-bit adder, output from a 3-input majority gate is inverted and input two times to a 5-input majority gate. Other inputs to the 5-input majority gate are same as those of the 3-input majority gate. The output of the 5-input majority gate is a sum while the output of the 3-input majority gate is the carry. Multiple 1-bit adders are concatenated to form an N-bit adder. The input signals are driven to first terminals of non-ferroelectric capacitors while the second terminals are coupled to form a majority node. Majority function of the input signals occurs on this node. The majority node is then coupled to a first terminal of a non-linear polar capacitor. The second terminal of the capacitor provides the output of the logic gate. A reset mechanism initializes the non-linear polar capacitor before addition function is performed.Type: ApplicationFiled: May 18, 2023Publication date: September 28, 2023Applicant: Kepler Computing, Inc.Inventors: Sasikanth Manipatruni, Yuan-Sheng Fang, Robert Menezes, Rajeev Kumar Dokania, Guarav Thareja, Ramamoorthy Ramesh, Amrita Mathuriya

Patent number: 11764790Abstract: A new class of logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates. Input signals in the form of digital signals are driven to non-linear input capacitors on their respective first terminals. The second terminals of the non-linear input capacitors are coupled a summing node which provides a majority function of the inputs. In the multi-input majority or minority gates, the non-linear charge response from the non-linear input capacitors results in output voltages close to or at rail-to-rail voltage levels. In some examples, the nodes of the non-linear input capacitors are conditioned once in a while to preserve function of the multi-input majority gates.Type: GrantFiled: May 21, 2021Date of Patent: September 19, 2023Assignee: KEPLER COMPUTING INC.Inventors: Rajeev Kumar Dokania, Amrita Mathuriya, Rafael Rios, Ikenna Odinaka, Robert Menezes, Ramamoorthy Ramesh, Sasikanth Manipatruni

Patent number: 11742860Abstract: A new class of logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates. Input signals in the form of digital signals are driven to non-linear input capacitors on their respective first terminals. The second terminals of the non-linear input capacitors are coupled a summing node which provides a majority function of the inputs. The majority node is then coupled driver circuitry which can be any suitable logic gate such as a buffer, inverter, NAND gate, NOR gate, etc. In the multi-input majority or minority gates, the non-linear charge response from the non-linear input capacitors results in output voltages close to or at rail-to-rail voltage levels. Bringing the majority output close to rail-to-rail voltage eliminates the high leakage problem faced from majority gates formed using linear input capacitors.Type: GrantFiled: June 22, 2022Date of Patent: August 29, 2023Assignee: Kepler Computing Inc.Inventors: Sasikanth Manipatruni, Rafael Rios, Neal Reynolds, Ikenna Odinaka, Robert Menezes, Rajeev Kumar Dokania, Ramamoorthy Ramesh, Amrita Mathuriya
