Abstract
A memory controller is provided that drives data and a corresponding first data strobe to a plurality of endpoints. Each endpoint is configured to register the received data from the memory controller responsive to the first data strobe and then to re-register the received data responsive to a second data strobe. A clock synchronization circuit functions to keep the received first data strobe at one of the endpoints sufficiently synchronous with the second data strobe.
