Patent number: 12640187Abstract: Described herein is a method and apparatus to reduce electric displacement and polarization target for a memory bit-cell. In at least one embodiment, electric displacement and polarization target for non-linear polar material based memory bit-cells is reduced by re-architecting the memory. In at least one embodiment, memory is architected to reduce electric displacement and polarization target by reducing capacitance on sense line or bit-line for bit-cell being accessed or written to. In at least one embodiment, memory arrays are actively split into two or more sub-arrays and routing capacitance is reduced, which in turn reduces capacitance on sense line or bit-line.Type: GrantFiled: November 9, 2023Date of Patent: May 26, 2026Assignee: Kepler Computing Inc.Inventors: Rajeev Kumar Dokania, Erik Unterborn, Biswajeet Guha, Pramod Kolar, Mustansir Yunus Mukadam, Darshak Doshi, Tanay Gosavi, Amrita Mathuriya, Debo Olaosebikan, Sasikanth Manipatruni

Patent number: 12412611Abstract: Described herein is a read and write scheme to improve memory reliability. In at least one embodiment, one or more circuitries are provided to perform logic 0 write operation in a first phase and logic 1 write operation in a second phase for a plurality of bit-cells controlled by a word-line. In at least one embodiment, an individual bit-cell comprises a transistor having a gate terminal coupled to the word-line; and a capacitor including non-linear polar material, wherein the capacitor has a first terminal coupled to a plate-line and a second terminal coupled to the transistor, wherein a source or drain terminal of the transistor is coupled to a bit-line.Type: GrantFiled: April 28, 2023Date of Patent: September 9, 2025Assignee: Kepler Computing Inc.Inventors: Rajeev Kumar Dokania, Pramod Kolar, Mustansir Yunus Mukadam, Darshak Doshi, Biswajeet Guha, Tanay Gosavi, Amrita Mathuriya, Debo Olaosebikan, Sasikanth Manipatruni

Patent number: 12147747Abstract: A computer-aided design (CAD) tool is provided for logic optimization and synthesis. The CAD tool executes a process that involves optimizing power, performance, and area (PPA) of a logic circuit by minimizing a number of CMOS gates, and majority and/or minority gates in the circuit and its depth. The CAD tool implements a methodology of optimizing logic synthesis based on a mix of standard cell libraries (such as AND, OR, NAND, NOR, XOR, Multiplexer, full adder, half adder, etc.) and varying input majority and minority gates (where the number of inputs in the minority and majority gates could vary as odd numbers from 3 and above). The standard cell libraries cells may contain minority and/or majority gates.Type: GrantFiled: December 11, 2023Date of Patent: November 19, 2024Assignee: Kepler Computing Inc.Inventors: Ikenna Odinaka, Sasikanth Manipatruni, Darshak Doshi, Rajeev Kumar Dokania, Amrita Mathuriya

Patent number: 11967954Abstract: A class of complex logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates. At least one input to an individual multi-input majority gate is a fixed input. Other inputs 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 summing node is coupled to a CMOS logic. Leakage through the capacitors is configured such that capacitors of a majority gate have substantially equal leakage, and this leakage has a I-V behavior which is symmetric. As such, reset device(s) on the summing node are not used. The non-linear charge response from the non-linear input capacitors results in output voltages close to or at rail-to-rail voltage levels, which reduces the high leakage problem faced from majority gates that use linear input capacitors.Type: GrantFiled: April 20, 2022Date of Patent: April 23, 2024Assignee: KEPLER COMPUTING INC.Inventors: Amrita Mathuriya, Rafael Rios, Ikenna Odinaka, Darshak Doshi, Rajeev Kumar Dokania, Sasikanth Manipatruni
