Diffrence between ddr2 and dd3 || ddr explanation 2020

DDR 2, DDR 3, DDR are new versions of RAM memory. In which DDR3 is a more advanced version, it comes with more capabilities such as higher data transfer speed, lower power consumption, memory reset option, more memory. The main difference between DDR 2 and DDR 3 is the data rate, where DDR 3 provides twice as much speed as DDR 2.

DDR 2, DDR 3

With the speed of technology, several versions have been developed to make memory faster, of which DDR is a new version. Several techniques are used to increase the speed of bit transfer from pin to chip. Effectively clock speeds are used that allow data to be transferred externally to the rising and falling edge of the clock, which is why these memory are known as double data rate memory.
