DDR3 SDRAM
- Double data rate three synchronous dynamic random access memory
- Transfers data at twice the rate of DDR2
- Higher bus rates and peak rates than earlier memory technologies
- Provides a reduction in power consumption of 30% compared to DDR2 modules
- 1.5V supply voltage, compared
to DDR2's 1.8V
