Overview

The Client Clock Driver (CKD) is a first of its kind device designed specifically for Client DIMMs:  

  • small-outline DIMMs (SODIMMs)
  • unbuffered DIMMs (UDIMMs)
  • high-performance gaming DIMMs and  
  • memory down applications

The CKD buffers the clock between the host controller and DRAM, which is a new requirement for DDR5 client DIMMs operating at speeds of 6400 MT/s and higher.

The CKD supports speeds up to 7200 MT/s.

The new clock driver has I2C and I3C sideband access to enable asynchronous control and provides access to internal control words for configuring device features and adapting to different SODIMM and UDIMM configurations and memory down applications.
