Besides, DDR is strictly called DDR SDRAM, which is commonly called DDR, and some beginners also commonly see DDR SDRAM, which is regarded as SDRAM. DDR SDRAM, an acronym for Double Data Rate SDRAM, means Double-Data synchronous dynamic random access memory. DDR memory is developed on the basis of SDRAM memory, and SDRAM production system is still used, so for memory manufacturers, DDR memory production can be realized only by slightly improving equipment for manufacturing common SDRAM, and cost can be effectively reduced.
The SDRAM only transmits data once in a clock period, and the data transmission is carried out in the rising period of the clock; the DDR memory transfers data twice in one clock cycle, and can transfer data once in the rising period and the falling period of the clock, so the DDR memory is called a double-rate synchronous dynamic random access memory. DDR memory can achieve higher data transfer rates at the same bus frequency as SDRAM.
Compared with SDRAM: DDR uses a more advanced synchronous circuit, so that the main steps of transmission and output of the designated address and data are independently executed and are kept completely synchronous with the CPU; DDR uses DLL (Delay Locked Loop) technology, and when data is valid, the memory controller can use this data filter signal to pinpoint the data, output it every 16 times, and resynchronize the data from different memory modules. DDR essentially doubles the speed of SDRAM without increasing the clock frequency, allowing data to be read on both the rising and falling edges of the clock pulse, thus doubling its speed as standard SDRA.
