WebJun 25, 2012 · DDR (double data rate), as the name suggests, transfers two chunks of data per clock cycle and hence achieve twice the performance as compared to the memory without this feature. It is for … WebDuring a write, DQS groups launch at separate times to coincide with a clock arriving at components on the DIMM, and must meet the timing parameter between the …

DDR2 SDRAM Device Operating & Timing Diagram
WebNov 2, 2014 · It does this by using sophisticated methods including on-die termination (ODT), read/write leveling (using a “fly-by” topology to deliberately introduce flight-time skew, thereby avoiding simultaneous switching noise), Vref tuning, CMD/CTL/ADDR timing training, and other methods. WebDDR timing variations are mainly associated with board design and selected DDR device type. To a lesser extent, DDR timing are influenced by parametric deviations between manufactured i.MX53 ICs, DDR devices, and boards. Changing ambient temperature and product age can also have a minor effect on DDR timing.
