  • Patent number: 12155383
    Abstract: A multiplier cell is derived from a 1-bit full adder and an AND gate. The 1-bit full adder is derived from majority and/or minority gates. The majority and/or minority gates include non-linear polar material (e.g., ferroelectric or paraelectric material). A reset mechanism is provided to reset the nodes across the non-linear polar material. The multiplier cell is a hybrid of majority and/or minority gates and complementary metal oxide semiconductor (CMOS) based inverters and/or buffers. The adder uses a non-linear polar capacitor to retain charge with fewer transistors than traditional CMOS sequential circuits. The non-linear polar capacitor includes ferroelectric material, paraelectric material, or non-linear dielectric. Input signals are received by respective terminals of capacitors having non-linear polar material. The other terminals of these capacitors are coupled to a node where the majority function takes place for the inputs.

  • Patent number: 12147747
    Abstract: 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.

  • Publication number: 20240379733
    Abstract: Ferroelectric capacitor is formed by conformably depositing a non-conductive dielectric over the etched first and second electrodes, and forming a metal cap or helmet over a selective part of the non-conductive dielectric, wherein the metal cap conforms to portions of sidewalls of the non-conductive dielectric. The metal cap is formed by applying physical vapor deposition at a grazing angle to selectively deposit a metal mask over the selective part of the non-conductive dielectric. The metal cap can also be formed by applying ion implantation with tuned etch rate. The method further includes isotopically etching the metal cap and the non-conductive dielectric such that non-conductive dielectric remains on sidewalls of the first and second electrodes but not on the third and fourth electrodes.

  • Publication number: 20240380403
    Abstract: 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.

    Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) may register a configuration of one or more RAN entities to a network repository function (NRF). The AMF may register information associated with a device with a UDM. A network data analytics function (NWDAF) may perform RAN discovery via the NRF, the UDM, or both. The NWDAF may receive an analytics request from a device, and the NWDAF may query the NRF, the UDM, or both for information about one or more targets of the analytics request, and the NWDAF may receive such information from the NRF, the UDM, or both. The NWDAF may transmit a data collection request to the RAN and the NWDAF may receive data back from the RAN.

  • Patent number: 12126339
    Abstract: A new class of logic gates are presented that use non-linear polar material. The logic gates include multi-input majority gates and threshold gates. Input signals in the form of analog, digital, or combination of them are driven to first terminals of non-ferroelectric capacitors. The second terminals of the non-ferroelectric capacitors 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 capacitor comprising non-linear polar material. The second terminal of the capacitor provides the output of the logic gate, which can be driven by any suitable logic gate such as a buffer, inverter, NAND gate, NOR gate, etc. Any suitable logic or analog circuit can drive the output and inputs of the majority logic gate. As such, the majority gate of various embodiments can be combined with existing transistor technologies.

  • Publication number: 20240347397
    Abstract: A method to deposit a multi-layer stack for device applications includes implementing a model driven target selection for deposition. One or more targets may be procured with an initial stoichiometric composition or elemental purity. The targets may be utilized to form the multi-layer stack, and measurements may be made of chemical composition and electrical properties of the multi-layer stack. The measurements may be compared to reference target values and if measurement results are not within tolerance, the composition of the targets can be changed to yield a successive multi-layer stack. The process can be iterated until measurement results are within tolerance of target results. Additional experimentation with post deposition thermal anneal can be performed to optimize multi-layer stack properties.
