DDR6 looks set to double data speeds over DDR5, with DDR6-21000 being the ultimate target

Every processor is limited in some way by the speed of memory, and DRAM manufacturers are pushing ahead with the development of DDR6, the next generation of RAM after DDR5. Details from Synopsys show that the technology is on target to finalise next year, with data speeds of up to 17,600 MT/s and the potential to reach 21,000 MT/s or DDR6-21000.

News of the progress, plus information about the fundamental changes in DDR6 compared to DDR5, were given via a presentation by Synopsys, who manufacture RAM controllers and interfaces.
