Question: 1 / 525

DDR RAM operates at how many volts?

1.8V

2.5V

The correct answer is that DDR RAM operates at 2.5 volts. This voltage standard was developed during the design of DDR (Double Data Rate) SDRAM, which significantly improves performance compared to its predecessor, SDR SDRAM. The lower voltage of 2.5V allows for reduced power consumption and heat generation, making it more efficient for modern computing needs.

Higher voltage options such as 3.3V and 5V are associated with older RAM technologies and would not be suitable for DDR RAM. Similarly, while 1.8V is relevant to later memory technologies like DDR2 and DDR3, it does not apply to the original DDR RAM, which is the focus of the question.
