A shift register unit, a gate line driving device includes multiple stages of the shift register units, and a driving method for being applied to the shift register unit; the shift register unit includes: an input module connected between an input terminal and a pull-up node, and configured to charge the pull-up node; an output module connected between the pull-up node, a first clock signal terminal and an output terminal, and configured to output to the output terminal a first clock signal received at the first clock signal terminal; a pull-up node reset module connected between a reset terminal, a pull-down node and the pull-up node, and configured to reset the pull-up node; and an output reset module connected between a second clock signal terminal, the pull-down node and the output terminal, and configured to reset the output terminal.

A method for hardware assisted data lookup in a storage unit is provided. The method includes formatting data in at least one of a plurality of data formats for storage in the storage unit. The method includes configuring a logic unit with one or more parameters associated with the plurality of data formats and identifying incoming data with the one or more parameters as an instruction for execution.

In a programmable logic integrated circuit, providing a spare circuit in preparation for the occurrence of a defective element results in a redundant circuit configuration. A programmable logic integrated circuit according to the present invention has: a plurality of logic blocks; a switch block for switching the connections between row and column wires by nonvolatile switch elements for switching; and a shifter block for connecting an input/output wire to said switch block. The shifter block includes a redundant wire and is equipped with nonvolatile switch elements for shifting that control the connections of the wires constituting said redundant wire and said row wires.
