Multiple choice general knowledge science & technology Expand DDR SDRAM Dual Data Rate Segmented Dynamic Random Access Memory Dual Data Rate Synchronus Dynamic Random Access Memory Double Data Rate Synchronus Dynamic Random Access Memory Double Data Rate Systematic Dynamic Random Access Memory Reveal answer Fill a bubble to check yourself C Correct answer Explanation DDR SDRAM stands for Double Data Rate Synchronous Dynamic Random Access Memory. DDR means it transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate memory.
