Double Data Rate SDRAM (DDR SDRAM) chips are even faster than SDRAM chips because which of the following is true?
A)They transfer data twice for each clock cycle.
B)They are synchronized to the system clock.
C)They do not have to be re-energized as often.
D)They use pipelining techniques.

Question

Quizplus · Accepted Answer

DDR SDRAM chips transfer data twice for each clock cycle, which is why they are faster than regular SDRAM chips. This is known as double data rate technology. The other options (B, C, and D) are features that may contribute to the performance of DDR SDRAM, but they are not the primary reason why DDR SDRAM is faster than regular SDRAM.
