Abstract

See full text

The operation speed of a semiconductor device is improved. The semiconductor device includes a first memory region and a second memory region; in the semiconductor device, a first memory cell in the first memory region is superior to a second memory cell in the second memory region in data retention characteristics such as a large storage capacitance or a large channel length-channel width ratio (L/W) of a transistor. When the semiconductor device is used as a cache memory or a main memory device of a processor, the first memory region mainly stores a start-up routine and is not used as a work region for arithmetic operation, and the second memory region is used as a work region for arithmetic operation. The first memory region becomes an accessible region when the processor is booted, and the first memory region becomes an inaccessible region when the processor is in normal operation.
