PROBLEM TO BE SOLVED: To provide a dual chip package, which is memory chips including memories respectively having different address systems, capable of freely accessing to the memories of the respective memory chips. SOLUTION: The dual chip package includes two memory chips. The respective memory chips include a buffer memory and a flash memory having different address systems. The respective memory chips include a register for storing first and second flag signal respectively indicating selection of the memory chip and selection of the buffer memory, a comparison circuit for respectively comparing the first and second flag signals stored in the register with a reference signal, and respectively generating a flash access signal and a buffer access signal, and a controller for responding to the flash access signal and the buffer access signal and controlling the buffer memory and the flash memory. Thereby, the buffer memory and the flash memory of the respective memory chips are freely accessed. COPYRIGHT: (C)2005,JPO&NCIPI
