PURPOSE:To carry out other internal processing especially in a write mode by storing the write related information delivered from a processor together with a write instruction until a common bus is available. CONSTITUTION:When data are written to a memory 3, a processor 2 outputs a write instruction and also the write related information, i.e., the data to be written and the address information. The write related information is stored in a write information store means 4. Then the processor 2 is released from the access processing of the memory 3 and can perform other processing. While the write related information stored in the means 4 is used for the write processing that is carried out by a write control means (not shown here) which subjected to the write instruction, for example, and in its own memory access cycle. |
