  • Patent number: 11170845
    Abstract: Certain aspects of the present disclosure are directed to a memory system. The memory system generally includes a word line (WL) driver circuit comprising a transistor coupled between a WL of a memory and a reference potential node. The memory system also includes a clamping circuit having logic configured to generate a control signal to drive a gate of the transistor such that the control signal is floating when the first head switch is open, and a first head switch coupled between a voltage rail and a supply input of the logic.

  • Patent number: 9941881
    Abstract: A latch circuit includes an AND-NOR gate, a NAND gate, and a NOR gate. The AND-NOR gate includes a first AND-input configured to receive input data and a second AND-input coupled to an output of the NAND gate. The AND-NOR gate includes a NOR-input coupled to an output of the NOR gate, and an output configured to generate output data. The NAND gate includes a first input coupled to the output of the AND-NOR gate and a second input configured to receive a clock signal. The NOR gate includes a first input coupled to the output of the AND-NOR gate and a second input configured to receive a complementary clock signal. During a first half clock cycle, the AND-NOR gate passes the data from the input to the output. During a second half clock cycle, the feedback configuration of the AND-NOR gate and the NOR gate latches the data.
