Abstract:
A semiconductor integrated circuit device includes a first semiconductor device and a second semiconductor device, first and second buffer circuits, a data bus, and a control circuit. The semiconductor integrated circuit device executes data transmission/reception between the first and second semiconductor devices. The first and second buffer circuits store data. The data bus transmits the data between the first and second buffer circuits. The first semiconductor device reads out the transfer data into the first buffer circuit. The control circuit transfers the transfer data, which is stored in the first buffer circuit, to the second buffer circuit via the data bus. The control circuit acquires a right of use of the data bus after the first semiconductor device writes the transfer data into the first buffer circuit, and disclaims the right of use of the data bus after the transfer data is transferred to the second buffer circuit.
