  • E-fuse array circuit
    Patent number: 9123428
    Abstract: An e-fuse array circuit includes: an e-fuse transistor of a vertical gate type configured to have a gate for receiving a voltage of a program gate line and have one between a drain terminal and a source terminal floating; and a selection transistor of a buried gate type configured to have a gate for receiving a voltage of a word line gate line and electrically connect/disconnect the other one between the drain terminal and the source terminal with a bit line.
    Type: Grant
    Filed: June 27, 2014
    Date of Patent: September 1, 2015
    Assignee: SK Hynix Inc.
    Inventors: Sungju Son, Youncheul Kim, Sungho Kim, Dongue Ko
  • E-fuse array circuit
    Patent number: 9007802
    Abstract: An e-fuse array circuit includes a program gate line and a word line gate line that are stretched in parallel to each other, and a metal line formed over the program gate line and the word line gate line to cover the program gate line and the word line gate line, the metal line connected to the program gate line through a plurality of contact plugs disposed at a given distance.
