Patent ID: 7838960

Claim:
An integrated circuit device comprising: a high-speed interface circuit block that transfers data through a serial bus; and a driver logic circuit block that generates a display control signal, a first-conductivity-type transistor included in the high-speed interface circuit block being formed in a second-conductivity-type well, a second-conductivity-type transistor included in the high-speed interface circuit block being formed in a first-conductivity-type well formed in a second-conductivity-type substrate to enclose the second-conductivity-type well, and a first-conductivity-type transistor and a second-conductivity-type transistor included in the driver logic circuit block being formed in a region other than a region of the first-conductivity-type well for the high-speed interface circuit block, the high-speed interface circuit block including: a physical layer circuit including a receiver circuit that receives serial data through the serial bus; and a high-speed interface logic circuit including a serial/parallel conversion circuit that converts serial data received through the serial bus into parallel data, the high-speed interface logic circuit being disposed between the physical layer circuit and the driver logic circuit block, and the physical layer circuit being disposed so that the physical layer circuit and the driver logic circuit block are not adjacently disposed.
