Stands for "Double Data Rate." It is an advanced version of SDRAM, a type of computer memory. DDR-SDRAM, sometimes called "SDRAM II," can transfer data twice as fast as regular SDRAM chips. This is because DDR memory can send and receive signals twice per clock cycle. The efficient operation of DDR-SDRAM makes the memory great for notebook computers since it uses up less power.
They are RAM (memory) chips for use in a computer.
The term DDR SDRAM refers to the phrase "double data rate synchronous dynamic random access memory". DDR SDRAM is simply a faster version of SDRAM in which data travels at a double rate. If your computer specs say that it uses DDR SDRAM it can take DDR SDRAM, but not SDRAM. DDR is 184 pins and has a notch in the bottom near the center and you will be unable to put DDR in an SDRAM mother board and also unable to put SDRAM in a DDR motherboard. Recently a new type of RAM has been introduced to market called DDR2. DDR2 is its own type and will not fit into a DDR motherboard. Hope this helps. Peace.
DDR SDRAM The Double Data Rate SDRAM is a RAM standard created by JEDEC. DDR SDRAM is the most common video RAM teshnology found on recent video cards. DDR SDRAM is designed to transfer data at speeds twice that of conventional SDRAM by transferring data on both the rising and falling parts of the processing clock cycle.
In SDRAM, rising and falling edges are the opposite edges of a memory module through which data can be transferred. SDRAMs that are designed this way are called DDR (double data rate) SDRAMs.
DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory) transfers data twice per clock cycle. It achieves this by transferring data on both the rising and falling edges of the clock signal, effectively doubling the data rate compared to single data rate (SDR) SDRAM. This allows DDR SDRAM to provide higher bandwidth without increasing the clock frequency.
Full form of DDR is Double Data Rate. DDR-SDRAM : Double Data Rate Synchronous Dynamic Random Access Memory.
DDR-SDRAM
By transferring data on both the rise and fall of the clock speed
SDRAM and DDR RAM are memory integrated circuits used in computers. The difference between the two is the speed because SDRAM is a single data rate which is slower than DDR RAM that stands for the double data rate. Which means the chip reads or writes two words of data per clock cycle.
DDR-SDRAM
Data path widths for DDR SDRAM can be at least 8, 16, 32, 64 and 72 bits, according to a DDR SDRAM contoller chip manufacturer.
