PROBLEM TO BE SOLVED: To provide a system capable of performing more flexible arithmetic processing by issuing a command from a packet type memory LSI with arithmetic processing function while using a command bus and a control method therefor. SOLUTION: The packet type memory bus of the packet type memory system with arithmetic processing function is provided with a ready signal 17 and a bus arbitrate signal 18. Then, the end of arithmetic processing is reported while using the ready signal line 17 and it is arbitrated while using the bus arbitrate signal line 18 whether a command bus 15 is to be occupied by a memory controller LSI 11 or a packet type memory LSI 13 with arithmetic processing function.
