Type of DDR: 1, DDR SDRAM: Double Data Rate Synchronous Dynamic Random Access Memory, double data rate synchronous dynamic random access memory; 2, DDR2 SDRAM: Double-Data-Rate Two Synchronous Dynamic Random Access Memory, second generation double data rate synchronous dynamic random access memory; 3, DDR3 SDRAM: Double-Data-Rate Three Synchronous Dynamic Random Access Memory, the third generation double data rate synchronous dynamic random access memory; 4, DDR4 SDRAM: Double-Data-Rate Fourth Synchronous Dynamic Random Access Memory, the fourth generation of double data rate synchronous dynamic random access memory. The development of DDR: SDRAM DDR DDR2 DDR3 DDR4 It can be clearly seen that the interface between DDR, DDR2, DDR3 and DDR4 is not compatible, of course, the operating voltage is also different. (Except DDR4 is the interface of the desktop, the first three are the interfaces on the notebook) DDR SDRAM can transfer data twice in one clock cycle The DDR data transfer speed is twice the system clock frequency and can transmit data on the rising and falling edges of the strobe pulse. DDR2 data transfer speed is four times the system clock frequency DDR3 data transmission speed is 8 times the system clock frequency DDR development chart Samsung-DDR bandwidth and data transmission rate rising track GALOCE weight indicators are available in a variety of materials ranging from aluminum to 304 stainless steel enclosures and come with a variety of display options ranging from LCD, LED to large displays and wireless options. output RS232/RS485, can conntact the computer.
