According to the introduction, in the initial stage of DDR5, the UDIMM and SODIMM modules of desktop and notebook computers need to be paired with a PMIC and an SPD, and the CKD chip is not needed for the time being. When the DDR5 data rate reaches 6400MT/s and above, PC-side memory such as UDIMM and SODIMM modules for desktop and notebook PCs must use a dedicated clock driver chip (CKD chip) to buffer and drive the clock signals on the memory modules to meet the integrity and reliability requirements of high-speed clock signals.

Montage says CKD chips will be a new increment for the industry when the annual industry demand for CKD will be positively correlated with the number of DDR5 UDIMMs and SODIMMs (supporting rates of 6400MT / s and above) needed that year. Lantech plans to complete the development and shipment of mass-production versions of CKD chips by the end of 2023.

In addition, Montage Technology noted that the first-generation AI chip has completed the flow of engineering prototypes by the end of 2022 as scheduled, and a series of testing, verification and sample delivery will be carried out subsequently.
