DDR3 brief introduction >>>

DDR3 is a computer memory specification. It belongs to the SDRAM family of memory products, providing higher operating efficiency and lower voltage than DDR2 SDRAM.

New design>>>

1. 8-bit prefetch design, and DDR2 is 4bit prefetch, so the frequency of DRAM core is only 1/8 of the equivalent data frequency, and the core operating frequency (core frequency) of DDR3-800 is only 100MHz.

2. A point-to-point topology is used to reduce the burden on the address / command and control bus.

3. Using a production process below 100nm, the working voltage is reduced from 1.8V of DDR2 to 1.5V, and asynchronous reset (Reset) and ZQ calibration functions are added.

Memory improvements>>>

1.There are 4Bank and 8Bank designs in DDR2 SDRAM, the purpose is to meet the needs of future large-capacity chips. And DDR3 is likely to start from 2Gb capacity, so the initial logical bank is eight, and it is also ready for the future 16 logical banks.

2.Due to the addition of some features to DDR3, there will be an increase in pins. 8-bit chips are packaged in 78-ball FBGA, 16-bit chips are packaged in 96-ball FBGA, and DDR2 is available in 60/68 / 84-ball FBGA packages. And DDR3 must be green packaged and must not contain any harmful substances.

3.At the same time that DDR3 memory reaches high bandwidth, its power consumption can be reduced. Its core operating voltage is reduced from 1.8V of DDR2 to 1.5V. Related data predicts that DDR3 will save 30% of power consumption than current DDR2. no need to worry.

Performance advantage>>>

1. Higher operating frequency: Due to the reduced energy consumption, DDR3 can achieve a higher operating frequency, which to a certain extent compensates for the shortcomings of long delay time, and can also be one of the selling points of graphics cards. This is already shown on the graphics card.

2. Reduce the overall cost of the graphics card: DDR3 memory chip specifications are mostly 32M X 32bit, a single particle has a larger capacity, and 4 can form 128MB of video memory.

3. Good universality: Compared to DDR2, DDR3 has better compatibility with DDR2. Because key features such as pins and packaging remain unchanged, DDR3 graphics memory can be used with a slight modification of the DDR2 display core and publicly-designed graphics card.
