To Extend Memory Capacity And Bandwidth

Double Data Fee Synchronous Dynamic Random-Entry Memory (DDR SDRAM) is a sort of synchronous dynamic random-entry memory (SDRAM) extensively utilized in computer systems and different electronic gadgets. It improves on earlier SDRAM technology by transferring data on both the rising and falling edges of the clock signal, successfully doubling the information rate with out growing the clock frequency. This system, often called double data rate (DDR), permits for larger memory bandwidth whereas maintaining decrease energy consumption and decreased sign interference. DDR SDRAM was first introduced in the late nineteen nineties and is sometimes known as DDR1 to distinguish it from later generations. It has been succeeded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM, and DDR5 SDRAM, every offering additional improvements in speed, capability, and effectivity. These generations usually are not backward or ahead suitable, which means memory modules from completely different DDR versions cannot be used interchangeably on the identical motherboard. DDR SDRAM sometimes transfers sixty four bits of data at a time.
