What is a double data rate?
Double Data Rate(DDR):
The enhanced version of the synchronous dynamic random access memory (SDRAM) is Double Data Rate (DDR). SDRAM hangs tight for clock flags before reacting to control inputs. DDR utilizes both the falling and rising edges of the clock signal. The distinction among SDRAM and DDR isn't the speed, yet rather how frequently information is transmitted with each cycle. DDR moves information twice per clock cycle, while SDRAM imparts signs once per clock cycle. Similar frequencies are utilized for both. Be that as it may, DDR utilizes the two edges of the clock, while SDRAM utilizes just one. DDR is obsolete yet is still being used, for example, the analog-to-digital converter output. Refreshed DDR adaptations are DDR2 and DDR3.
