PROBLEM TO BE SOLVED: To provide a memory device for reducing access time required for reading-writing in a memory device having a memory for reading-writing a plurality of digit data composed of the prescribed bit number. SOLUTION: This memory device has a first RAM 162 and a second RAM 163 for storing the digit data composed of 1 bit or more, and outputting two or more of digit data. An output control circuit 27 takes out and outputs the continuous digit data among annular data by regarding the digit data as the annular data connected in a ring shape by connecting the two or more of digit data respectively outputted from the first RAM 162 and the second RAM 163. Thus, the digit data can be read out by one time read access. COPYRIGHT: (C)2005,JPO&NCIPI
