  • Patent number: 11888479
    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: 11863183
    Abstract: 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.

    Abstract: A reduced instruction set processor based on a memristor is provided. The memristor is a non-volatile device using a resistor to store “0” and “1” logic while implementing “implication logic” through applying a pair of voltages VCOND/VSET. Various data operations, logic operations, and arithmetic operations may be implemented based on the implication logic. The memristor is a computation and memory fusion device having great potential. A computer processor based on the memristor also becomes the research direction of the next-generation computer processor. The computer processor based on a memristor is designed according to the memory and computation fusion characteristic of the memristor. The processor is different from a traditional computer that must use a special memory and a calculator, and fuses computation and memory. Compared with a traditional computer, the speed, parallelism degree, and power consumption of the computer processor based on the memristor are greatly improved.
