Abstract
PURPOSE:To enable fast access and to attach flexibility on the connection of memory devices whose operational specifications are different, by generating the control signal of the memory device in an MS and the set signal of data, etc., by using the same clock as that of an SCU, and sending them with a various kinds of phases and the number of cycles. CONSTITUTION:The same clock 5 is used commonly in a storage control unit (SCU) 3 and a main storage (MS) 4, and a signal which controls the memory device of the MS 4 or the signal to set the data, etc., are generated by using the clock 5, and also, a means 51 which varies each signal by information representing a machine cycle or the operation specification of the memory device is provided in the MS 4. The SCU 3 and the MS 4 use the same clock source 5, and since all of the signals 60-66 are generated by using the clock source 5, no circuit for synchronization between the SCU 3 and the MS 4 is required, and also, it is possible to output the signal by the cycle and the phase with an arbitrary number. In such a way, it is possible to make access to the MS at high speed, and also, the attach the flexibility on the connection of the memory devices with different operational specifications.
