Montage Technology has unveiled its latest offering in the form of clock drivers for DDR5 memory modules. This is a significant development as consumer PC memory modules have not had access to such clock drivers until now. Montage Technology's M88DR5CK01 is the company's first DDR5 clock driver chip designed to be easily integrated into various RAM modules in the future.
The company has specifically highlighted the compatibility of these clock drivers with 'clocked' SO-DIMM and U-DIMM modules, both of which have their own clock drivers onboard. Additionally, Montage Technology has mentioned CAMM modules, a memory standard that has been in existence since last year.
According to Montage, these new chips conform to Jedec's DDR5CKD01 specification and support speeds of up to 7200MT/s. They offer support for double-sided bus access as well as I²C= and I3C interfaces. The primary function of these CKD chips is to buffer the clock signal between the memory controller and the memory within DDR5 modules.
This is a significant shift as traditionally, this process was only observed in server chips. However, with the advent of DDR5 technology, Montage Technology argues that it is imperative to incorporate this level of processing into consumer memory chips as well. It's worth noting that Montage is not the only player in this space, as Japanese company Renesas also introduced similar clock drivers last year.
