Question: 1 / 525

What is the primary feature of DDR RAM over SDRAM?

Higher voltage

More pins

Double data rate

The primary feature of DDR RAM over SDRAM is its ability to transfer data on both the rising and falling edges of the clock cycle, effectively doubling the data transfer rate compared to SDRAM, which only transfers data on one edge of the clock cycle. This enhancement allows DDR RAM to provide significantly improved performance for memory-intensive applications, making it a favorable option for modern computing systems.

In contrast, the other options, such as higher voltage, more pins, and fewer notches, do not specifically highlight what sets DDR RAM apart from SDRAM in terms of its fundamental operational capability. While DDR does indeed require different voltage levels and may have varying pin configurations, these aspects are secondary to its core advantage of facilitating a double data rate, which is essential for modern performance needs.
