The invention relates to a semiconductor device, which restricts the power consumed by memory access in a system on chip device. A system on chip device characterized by being provided with a processor that executes calculation processing in synchronization with a clock, a storage unit that operates out of synchronization with said clock, and an address transition detection unit that detects a transition in an address output to the storage unit from the processor, and by the address transition detection unit activating a word line of the storage unit when an address transition is detected. 本发明涉及一种半导体装置。本发明的半导体装置抑制系统单芯片器件中的存储器存取的耗电。本发明是一种系统单芯片器件，其特征在于具备：处理器，与时钟同步地执行运算处理；存储部，与所述时钟非同步地动作；以及地址转换检测部，对从所述处理器输出到所述存储部的地址的转换进行检测；且所述地址转换检测部当检测出所述地址的转换时，使所述存储部的字线有效。
