  • Bootstrap circuit
    Patent number: 9768685
    Abstract: Bootstrap circuit includes: a first transistor of first conductivity type having a first main electrode, a second main electrode and a control electrode connected to a first power supply terminal, a first node, and a second node, respectively; a second transistor of the first conductivity type having a first main electrode, a second main electrode, and a control electrode connected to the first power supply terminal, the second node and the first node, respectively; a first capacitor having a first end connected to the first node and a second end where a first boost pulse is applied; a second capacitor having a first end connected to the second node and a second end where a second boost pulse having opposite polarity to the first boost pulse is applied; and a boost output terminal which outputs boost voltage higher than first power supply voltage supplied to the first power supply terminal.

  • Memory circuit that updates and holds output signal based on fuse signal
    Patent number: 9595348
    Abstract: A memory circuit includes: a control part configured to output a control signal; a fuse circuit which is driven by the control signal and is configured to output a fuse signal whose signal level is determined based on a state of a first fuse element; and a holding circuit configured to update and hold a signal based on the fuse signal in response to the control signal output from the control part and output the held signal as an output signal.
