What does DDR stand for, computer wise?

Question

I only know it stands for Konami's Dance Dance Revolution.

This computer I'm on says,

"1.0 GB, PC3200 DDR SDRAM memory."

What kind of memory is this?

Answer 1

LMAO, Dance Dance Revolution? I love that game.

Anyways, DDR stands for
DDR SDRAM or double-data-rate synchronous dynamic random access memory, according to wikipedia.

To paraphrase Wikipedia, DDR SDRAM allows data to be written on the the rising and falling "edges" of the clock signal.

The clock signal is basically how fast the RAM can delete data from its memory, and write new data, etc. Being able to write data on the rising and falling of the clock signal is better than being only able to do so once per clock signal. DDR can do 2/clock signal.

You have good memory, PC3200 = DDR400 which is the highest official speed.

For your next PC, get DDR-2 RAM, at least, which is faster than DDR, or DDR-3 if that comes out.

Answer 2

DDR stands for double data rate .. DDR SDRAM or double-data-rate synchronous dynamic random access memory is a type of memory integrated circuit used in computers. It achieves greater bandwidth than the preceding single-data-rate SDRAM by transferring data on both the rising and falling edges of the clock signal (double pumped). This effectively nearly doubles the transfer rate without increasing the frequency of the front side bus. Thus a 100 MHz DDR system has an effective clock rate of 200 MHz when compared to equivalent SDR SDRAM, the “SDR” being a retrospective designation.

PC-3200: DDR-SDRAM memory module specified to operate at 200 MHz using DDR-400 chips, 3.200 GByte/s bandwidth

Answer 4

It means the memory is Double Data Rate Synchronous Dynamic RAM (Random Access Memory).

Answer 5

DDR - double data rate

DDR SDRAM - double-data-rate synchronous dynamic random access memory

Answer 6

this is particular brand of RAM (random access memory)
that you have inside your pc. RAM is essentially the short term memory of your computer, where most of the information is processed when your computer is busy.

having an appropriate amount of ram is generally the easiest (and cheapest) way of ensuring that your pc performs well and quickly.

ddr sdram (double-data-rate two synchronous dynamic random access memory) is a high speed storage medium, and the pc 3200 refers to the peak transfer capacity of your ram- how much information the memory chips can transfer at any given moment.

3200 is not that fast, though 1 gigabyte is a decent amount of memory for most home pc users. upgrading your RAM is easy- check out this link:

Answer 7

DDR in this case stands for "double data rate", i.e. it can transmit data at twice the speed of regular SD RAM.

Answer 8

double data rate synchronous dynamic random access memory for easy understading.

Answer 9

1GB, 1024MB of memory
pc3200, which is 400MHz
DDR, double data rate
SDRAM, synchronous dynamic random access memory

Answer 10

double-data-rate, so named because nearly doubles the speed at which it can transfer data over previous ("SDR") memory.
