PURPOSE:To automatically execute a retry by transferring access contents stored in an access result buffer to an access request buffer by the control of a signal control part in an interface circuit to a memory to execute the retry of access at the time of return of an error report from the memory. CONSTITUTION:When a signal sent from the memory to a control line 172 indicates error, error is discriminated by a signal control part 17 to generate control signal '1' on a control line 174. Then, driving circuits of buffer mechanisms 12-15 are operated to read out store data, which is stored at the time of access, from a load data buffer 12 and this data is stored in a store data buffer 15 again through a transfer line 122 and a gate circuit 152, and the memory address and the command stored in an end stack 13 are read out and are stored in an address buffer 14 through a transfer line 132 and a gate circuit 145. Thus, the retry is executed. |
