  • Patent number: 11501813
    Abstract: A high-density low voltage ferroelectric (or paraelectric) memory bit-cell that includes a planar ferroelectric or paraelectric capacitor. The memory bit-cell comprises 1T1C configuration, where a plate-line is parallel to a word-line, or the plate-line is parallel to a bit-line. The memory bit-cell can be 1TnC, where ‘n’ is a number. In a 1TnC bit-cell, the capacitors are vertically stacked allowing for multiple values to be stored in a single bit-cell. The memory bit-cell can be multi-element FE gain bit-cell. In a multi-element FE gain bit-cell, data sensing is done with signal amplified by a gain transistor in the bit-cell. As such, higher storage density is realized using multi-element FE gain bit-cells. In some examples, the 1T1C, 1TnC, and multi-element FE gain bit-cells are multi-level bit-cells. To realize multi-level bit-cells, the capacitor is placed in a partially switched polarization state by applying different voltage levels or different time pulse widths at the same voltage level.

  • Patent number: 11502959
    Abstract: A traffic flow based map cache refresh may be provided. A computing device may receive a dropped packet message when a packet associated with a flow having a destination and a source was dropped before it reached the destination. Next, in response to receiving the dropped packet message, a map request message may be sent to a Map Server (MS). In response to sending the map request message, a map response message may be received indicating an updated destination for the flow. A map cache may then be refreshed for the source of the flow based on the updated destination from the received map response message.

  • Patent number: 11502691
    Abstract: An adder uses 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 the 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 to the majority gates can be analog, digital, or a combination of them, which 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 non-linear polar capacitor. The second terminal of the capacitor provides the output of the logic gate.

  • Patent number: 11482270
    Abstract: A memory is provided which comprises a capacitor including non-linear polar material. The capacitor may have a first terminal coupled to a node (e.g., a storage node) and a second terminal coupled to a plate-line. The capacitors can be a planar capacitor or non-planar capacitor (also known as pillar capacitor). The memory includes a transistor coupled to the node and a bit-line, wherein the transistor is controllable by a word-line, wherein the plate-line is parallel to the bit-line. The memory includes a refresh circuitry to refresh charge on the capacitor periodically or at a predetermined time. The refresh circuit can utilize one or more of the endurance mechanisms. When the plate-line is parallel to the bit-line, a specific read and write scheme may be used to reduce the disturb voltage for unselected bit-cells. A different scheme is used when the plate-line is parallel to the word-line.

  • Patent number: 11482528
    Abstract: The memory bit-cell formed using the ferroelectric capacitor results in a taller and narrower bit-cell compared to traditional memory bit-cells. As such, more bit-cells can be packed in a die resulting in a higher density memory that can operate at lower voltages than traditional memories while providing the much sought after non-volatility behavior. The pillar capacitor includes a plug that assists in fabricating a narrow pillar.

  • Patent number: 11482990
    Abstract: A low power sequential circuit (e.g., latch) uses a non-linear polar capacitor to retain charge with fewer transistors than traditional CMOS sequential circuits. In one example, a sequential circuit includes pass-gates and inverters, but without a feedback mechanism or memory element. In another example, a sequential uses load capacitors (e.g., capacitors coupled to a storage node and a reference supply). The load capacitors are implemented using ferroelectric material, paraelectric material, or linear dielectric. In one example, a sequential uses minority, majority, or threshold gates with ferroelectric or paraelectric capacitors. In one example, a sequential circuit uses minority, majority, or threshold gates configured as NAND gates.
