  • Publication number: 20240071428
    Abstract: A device is disclosed and includes an input stage circuit, a switching circuit, and a first latch circuit. The input stage circuit generates a first input signal having a first voltage and a second input signal based on a third input signal. The switching circuit operates in response to a first control signal, and adjusts a voltage level of a first data line according to the first input signal and a voltage level of a second data line according to the second input signal. The first latch circuit is coupled to the switching circuit by the first data line and the second data line. The first latch circuit latches a data in response to the first control signal and a second control signal, and adjusts the voltage level of the first data line based on a second voltage different from the first voltage.

  • Patent number: 11915743
    Abstract: A latch formed from a memory cell includes a clock input terminal configured to receive a clock signal, complementary first and second data terminals, and a latch circuit. The latch circuit has first and second inverters. The first inverter has an input terminal coupled to the first data terminal, and the second inverter has an input terminal coupled to the second data terminal. A first pass gate transistor is coupled between an output terminal of the second inverter and the first data terminal. A second pass gate transistor is coupled between an output terminal of the first inverter and the second data terminal. The first and second pass gate transistors each have a gate terminal coupled to the clock input terminal. The input terminal of the first inverter is not directly connected to the output terminal of the second inverter, and the input terminal of the second inverter is not directly connected to the output terminal of the first inverter.
