Montage shows clock driver for DDR5 memory that should be able to reach 7200MT/s

Montage Technology has started producing clock drivers for DDR5 memory. Until recently, such clock drivers, or CKDs, were not available for memory strips for consumer PCs, but Montage says that is changing with the growth of DDR5.

Montage Technology says the M88DR5CK01 is the first DDR5 clock driver chip of the company that can be integrated into different types of RAM in the future. The company specifically mentions the 'clocked' versions of SO-DIMM and U-DIMM modules, which therefore have their own clock driver on board. Montage also mentions CAMM modules, a memory standard that has existed since last year. According to Montage, the new chips are compatible with Jedec's DDR5CKD01 specification and allow speeds of 7200MT/s. The chips support double-sided bus access and both I²C= and I3C interfaces. According to the company, the CKD chips are intended to be integrated into those DDR5 modules. There they buffer the clock signal between the memory controller and the memory. Previously, this process only occurred in server chips, but with the arrival of DDR5, Montage says that it is necessary to also process the technology in memory chips for consumers. By the way, Montage is not the first company to make such clock drivers; the Japanese Renesas started doing this last year.
