According to embodiments of the invention, an integrated configuration, flow and execution systems may be used to specify, control and record a history of processing of both semiconductor device experimental lots and production lots of wafers. The information recording medium comprises a main information area for recording or reproducing information and a recording area for environmental load information, which is recorded with an environmental load information of the information recording medium. A first feedback signal is generated based on the analog current signal. Further, at least one interface circuit is provided, the interface circuit capable of adjusting timing of signals associated with one or more of the memory controller and the at least one memory module.
