ABSTRACT:
An integrated circuit design method whereby memory instances are assigned to memory macros integrated within an integrated circuit. A plurality of memory instances operating at the same operation frequency are assigned to a single memory macro. A frequency multiplier which receives a first clock signal is arranged to generate a second clock signal through frequency multiplication of the first clock signal, and feeds the second clock signal to the plurality of memory instances. A control circuit which selects the memory instances in synchronization is arranged with the first clock signal.
