لقد شد إنتباهي سؤالك، فقمت بالبحث في جوجل ووجدت هذه الصحفة حول :
ووجدت أيضا توضيح حول 2T , 1T
وهي كالآتي :
Command Rate (CMD): The command rate specifies how many consecutive clock cycles need to be sent to the memory modules before the modules can send data. Because wires often have natural capacitance on them, sometimes it takes longer for a wire to transition from a 1 to a 0. The CMD setting is typically one or two clocks and can often be adjusted between the two. It's represented as 1T or 2T.
Q: What is the difference between 1T and 2T memory timings?
A: A 2T command rate means that commands are presented to DRAMs for two consecutive clocks, as opposed to one consecutive clock for a system with a 1T memory setting.
