Abstract

The present invention provides a memory device including a serial-parallel conversion section that converts serial data into parallel data, a parallel-serial conversion section that converts parallel data into serial data, and a parallel-parallel conversion section that changes a bit width of the parallel data. This memory device connects one external terminal to the serial-parallel conversion section and another external terminal to the parallel-serial conversion section when access using a serial interface is performed. On the other hand, the memory device connects a plurality of external terminals to the parallel-parallel conversion section when access using a parallel interface is performed, thereby enabling the memory device to occasionally realize parallel transfer of data while using a conventional package.
