As computer technology has advanced, so too have the types of memory they use. One of the newer, faster versions of memory developed is DDR (Double Data Rate) memory. The main concept behind DDR memory is that, by applying a row address to the chip, a larger number of bits are accessible at the same time within the chip. There are two common types of DDR memory: DDR2 and DDR3. In this blog, we will discuss both types and the main differences between the two.
