Abstract
Aspects of the embodiment provide a semiconductor integrated circuit including a control terminal coupled to a memory through a control bus, a data terminal coupled to the memory through a data bus, a memory controller coupled to the control terminal and the data terminal and a first master and a second master coupled to the memory controller, wherein the memory controller supplies a control signal corresponding to a memory access based on the first master and a control signal corresponding to a memory access based on the second master to the control terminal in synchronism with a rising edge and a falling edge of a clock signal, respectively, and the memory controller receives and outputs input/output data of the first master and input/output data of the second master at the data terminal in synchronism with the rising edge and the falling edge, respectively.
