Abstract
Technologies for converting quad data rates on a host interface to double data rates on a memory interface are described. One memory module includes a data buffer device with a host-side interface circuit that sends or receives first data to and from a host device at a quad data rate and a memory-side interface circuit that sends or receives second data to and from a set of memory devices at a first specified data rate that is less than the quad data rate. The memory module includes conversion circuitry to down-convert the first data at the quad data rate to the second data at the first specified data rate and up-convert the second data at the first specified data rate to the first data at the quad data rate.
