<p>A data transmitting/receiving system for exchanging data between a microprocessor (1) and an auxiliary memory device (10) connected to the microprocessor. The system has a plurality of common RAMs (24, 25) for transmission and receiving of the data. The state of use of each common RAMs is stored in memory means (26, 27) so that the data transmission is made through the common RAM (24) or (25) which is not being used, in accordance with the signal from the memory means, thus reducing the waiting time for the data transmission.</p> |
