  • Patent number: 8824234
    Abstract: A method of reading an eFuse in a column of eFuse memory cells includes electrically disconnecting a first end of the eFuse from a first electrical path. A second electrical path between a second end of the eFuse and a node is activated to bypass a third electrical path, where the third electrical path includes a diode device between the second end of the eFuse and the node. A footer coupled with the node is turned on.

  • Patent number: 8466732
    Abstract: An input of a first inverter is configured to serve as an input node. An output of the first inverter is coupled to an input of a second inverter. An output of the second inverter is configured to serve as an output node. An input of a third inverter is coupled to an input of the first inverter. A gate of a first NMOS transistor is coupled to an output of the third inverter. A drain of the first NMOS transistor is coupled to the second inverter. A source of the first NMOS transistor is configured to serve as a level input node. When the input node is configured to receive a low logic level, the output node is configured to receive a voltage level provided by a voltage level at the level input node.
