An apparatus and method for synthesis and screening of materials are disclosed. An interface processor of a wireless interface is configured to maintain a network connection while an application processor is in a low power mode. The main controller and the two or more peripheral controllers, to which the different addresses are respectively assigned, are interconnected using one serial bus. The method further includes depositing metal material on the exposed underlying epitaxial layer to form contact metal in electrical contact with source and drain regions, adjacent to the at least one gate structure. In this way, when there is a possibility that an output of read data will cause a resource competition, this read data is stored in a read buffer, and when there is no such possibility, then the read data can be externally outputted directly, thereby improving the throughput of read data output operations. Each subportion may include a respective plurality of microparticles distributed in a random fashion.
