Abstract
Provided is a semiconductor device that combines a NOR flash memory and a NAND flash memory. A stacked flash memory includes a NOR flash memory, a NAND flash memory, a controller, and an external bus that can input/output data in synchronization with a serial clock signal. When receiving a read command according to specifications of the NOR flash memory from the external bus, the controller responds the read command to cause a portion of specific data read from the NOR flash memory to be serially output, and then cause a remaining portion of the specific data read from the NAND flash memory to be serially output. In this way, data is read from the expanded NAND flash memory in the same manner as accessing the NOR flash memory.
