A system includes: a group of memory resources including a first memory node and a second memory node, the first memory node being connected to the second memory node over a switching fabric; and a synchronous clock source connected to the first memory node and the second memory node, the synchronous clock source to provide a synchronized clock signal to the first memory node and the second memory node to synchronize the first memory node with the second memory node. The first memory node and the second memory node are configured to encode memory data and decode encoded memory data using the synchronized clock signal, and/or to send and receive memory data to and from each other using the same synchronized clock signal.
