Nov 22, 2011. #4. The 66/100/133 MHz Single Data Rate (SDR) SDRAM is usually just referred to as SDRAM. DDR SDRAM was the next step, and generally it's referred to as DDR, however some people will refer to it as DDR1 if they're contrasting DDR and DDR2. DDR2 SDRAM was next, it's pretty much always just referred to as DDR2. DDR3 same story as DDR2. A Summary Of The DDR Memory Controller Standard—Wait, There Isn’t One!

Write Queue which dramatically expands the memory controller's visibility of processor behavior, at low implementation overhead. Through memory-centric modiﬁcation of existing policies, such as ... of 5-10ns for DDR through DDR3. Therefore, as DRAM IO frequencies increase, the number of cycles wasted between each access grows. Figure 1.
To accomplish the data rates exclusive to DDR3, special attention must be paid to signal integrity. Minimizing any impedance mismatch on the traces connecting the memory controller to the DRAM outputs will help reduce reflections and ringing on the signals. To help reduce these impedance discontinuities, a precision calibration scheme is intro-. The PL DRAM IP has been characterized and tested to identify the optimal drive strength, ODT, and V REF settings. This chapter provides the values that will always be used for the PL DRAM IP UltraScale and UltraScale+ DDR3 and DDR4 DRAM interfaces. The Memory Controller supports the following calibration routines. The first one is very simple. It is to mix DDR3-1333 DRAM modules with DDR3-1066 rated. In this case the DRAM controller of the chipset is programmed to operate at 533 MHz automatically. But if the user plans to upgrade system memory to the maximum 8 GB he will probably buy a pair of new DDR3-1333 modules with 4GB in data capacity.
