Abstract
A semiconductor integrated circuit includes a command generating unit configured to generate a plurality of second commands in response to a first command, each second command for indicating an operation sections of a corresponding anti-fuse circuit, and a plurality of anti-fuse circuits, each comprising an anti-fuse and configured to receives a corresponding second command and perform a rupture operation of the anti-fuse in response to the received corresponding second command.
Claims16
A semiconductor integrated circuit, comprising:
- a command generating unit configured to generate a plurality of second commands in response to a first command, each second command for indicating an operation section of a corresponding anti-fuse circuit;
- and
- a plurality of anti-fuse circuits, each comprising an anti-fuse and configured to receive a corresponding second command and perform a rupture operation of the anti-fuse in response to the received corresponding second command,
- wherein the command generating unit comprises:
- a source signal generating unit configured to generate a source signal in response to a reset signal and the first command;
- and
- a sequential command output unit configured to be reset in response to the reset signal and configured to sequentially output the plurality of second commands in response to the first command and the source signal.
A method for driving a semiconductor integrated circuit, the method comprising:
- generating a rupture source signal in response to a reset signal and a first rupture command;
- sequentially generating a plurality of second rupture commands in response to the first rupture command and the rupture source signal, each indicating an operation section for programming a corresponding anti-fuse;
- and
- programming the corresponding anti-fuse in response to each of the second rupture commands.
