Abstract
A semiconductor device includes a main processor, a normally-off processor, and at least one oxide semiconductor random access memory (RAM). The normally-off processor includes at least one oxide semiconductor transistor. The main processor is connected to the normally-off processor, and a clock rate of the main processor is higher than a clock rate of the normally-off processor. The oxide semiconductor RAM is connected to the normally-off processor. An operating method of the semiconductor includes backing up data from the main processor to the normally-off processor and/or the oxide semiconductor RAM.
Claims7
A semiconductor device, comprising:
- a main processor;
- a normally-off processor comprising at least one oxide semiconductor transistor, wherein the main processor is connected to the normally-off processor, and a clock rate of the main processor is higher than a clock rate of the normally-off processor;
- and
- at least one oxide semiconductor random access memory (RAM) connected to the normally-off processor, wherein the normally-off processor and the oxide semiconductor RAM are integrated in one die, and the oxide semiconductor RAM comprises a dynamic random access memory (DRAM) shared by the main processor and the normally-off processor, wherein the main processor and the normally-off processor are disposed on different dies.
