DDR3 SDRAM, the latest generation of RAM

DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is random access memory interface technology used for high bandwidth data storage computer work or other digital electronic devices. DDR3 SDRAM is part of a family of technologies and is one of many DRAM (Dynamic Random Access Memory)
DDR3 is the change from DDR2 with a variety of technologies to be upgraded but the two types of SDRAM is not compatible with each other. The principal advantage of DDR3 is the ability to transfer data twice the level of DDR2 (I / O on 8 × data rate memory cells it contains), thus enabling a higher level bus and a higher peak level than previous memory technologies. In addition, the DDR3 standard allows for chip capacity of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes.
With data transfer 64-bits in one clock per memory modules, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bit / byte). So the memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB / s.
