    摘要: A neuromorphic memory circuit including a programmable resistive memory element, an axon LIF line to transmit an axon LIF pulse, and a dendrite LIF line to build up a dendrite LIF charge over time. A first transistor provides a discharge path for the dendrite LIF charge through the programmable resistive memory element when the axon LIF line transmits the axon LIF pulse. An axon STDP line transmits an axon STDP pulse. The axon STDP pulse is longer than the axon LIF pulse. A dendrite STDP line is configured to transmit a dendrite STDP pulse after voltage at the dendrite LIF line falls below a threshold voltage. A second transistor is coupled to the axon STDP line and the programmable resistive memory element. The second transistor provides an electrical path for the dendrite STDP pulse through the programmable resistive memory element when the axon STDP line transmits the axon STDP pulse.

    摘要: A method of manufacturing a bipolar junction transistor (BJT) array may include forming a substrate of doped silicon and forming a plurality of BJTs on the substrate. Each of the BJTs may have a first region and a second region sandwiching a base region vertically. The first region may be in contact with the substrate, where the BJTs are formed in a first row and a second row. The first row and the second row may each have BJTs separated from one another by a word line distance and the first row and second row may be separated by a bit line distance. A plurality of word line contacts may be formed laterally enclosing and electrically connected to each base region of the BJTs. The word line contacts may have a lateral thickness more than one half the word line distance and less than one half the bit line distance.
