Semiconductor device
A semiconductor device includes an input/output cell, an IO power supply cell, a core power supply cell, and a core logic circuit arranged on a chip, and the core power supply cell includes an ESD protection circuit. The input/output cell includes a level shifter circuit and the level shifter circuit is arranged in the input/output cell. The core logic circuit is arranged outside the input/output cell. The core power supply cell is not arranged in the same row as the input/output cell, but is arranged in a third region provided between a first region in which the input/output cell and the IO power supply cell are arranged and a second region in which the core logic circuit is arranged.
1 . A semiconductor device in which an input/output cell, an IO power supply cell, a core power supply cell, and a core logic circuit are arranged on a chip,
wherein the core power supply cell includes an ESD protection circuit,
wherein the input/output cell includes a level shifter circuit and the level shifter circuit is arranged in the input/output cell,
wherein the core logic circuit is arranged outside the input/output cell,
wherein the core power supply cell is not arranged in the same row as the input/output cell, but is arranged in a third region provided between a first region in which the input/output cell and the IO power supply cell are arranged and a second region in which the core logic circuit is arranged, and
wherein the core power supply cell is formed such that a long side of external dimensions thereof is shorter than a long side of an outer shape of the IO power supply cell, and a short side of external dimensions thereof is equal to or greater than a short side of the outer shape of the IO power supply cell.
2 . The semiconductor device according to claim 1 ,
wherein the core power supply cell is not arranged between the input/output cell and the core logic circuit, but is arranged in a fourth region between the IO power supply cell and the core logic circuit.
