Abstract:
A semiconductor integrated circuit device includes a first block, a second block, and a control section. The first block includes a first fuse, a first switching configured to write data to the first fuse, a first holding portion capable of holding a first instruction, and a first instruction portion configured to turn on the first switching when a second instruction is given thereto with the first instruction. The second block includes a second fuse, a second switching configured to write data to the second fuse, a second holding portion capable of holding the first instruction, and a second instruction portion configured to turn on the second switching when the second instruction is given thereto with the first instruction. The control section issues the second instruction at a point in time when the first instruction is held in the first and second holding portions.
