Abstract:
A computer program product and a hub device for deriving clocks in a memory system are provided. The computer program product includes a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method. The method includes receiving a reference oscillator clock at the hub device. The hub device is in communication with a controller channel via a controller interface and in communication with a memory device via a memory interface. A base clock operating at a base clock frequency is derived from the reference oscillator clock. A memory interface clock is derived by multiplying the base clock by a memory multiplier. A controller interface clock is derived by multiplying the base clock by a controller multiplier. The memory interface clock is applied to the memory interface and the controller interface clock is applied to the controller interface.
