ABSTRACT:
Data processing system including memory device having even-numbered addresses and odd-numbered addresses in which both an even-numbered address and an odd-numbered address are accessed in the long data bit length mode and either an even-numbered address or an odd-numbered address is accessed in the short data bit length mode, comprising a switching circuit 200 for carrying out the data communication with an odd-numbered address through a high-order data bus 6 or a low-order data bus 5 in the short data bit length mode, and a switching circuit 150 for carrying out the data communication with an odd-numbered address through the low-order data bus 5 in both the long and short data bit length modes. By virtue of this structure, the data communication through the low-order data bus only is made possible for both an even-numbered address and an odd-numbered address in the short data bit length mode.
