DDR3 SDRAM

Third generation DDR memory leaps greatly forward in data transfer rate and power management. DDR3 provides even higher bandwidth than DDR2 due to the 8-bit prefetch buffer (4-bit prefetch of DDR2, and 2-bit of DDR). The advanced fabrication technology allows lower operating currents and voltages (1.5V, compared to 1.8V of DDR2) and thus enhances thermal performance. Successor to DDR2, DDR3 is considered to replace DDR and DDR2 in coming years. DDR3 memory modules take the form of 240-pin DIMMs, and are not compatible with DDR2 memory slots.
