Which memory technology is known for doubling the max bandwidth of SDRAM?

The correct answer is DDR, which stands for Double Data Rate. DDR memory technology effectively doubles the maximum bandwidth of Standard Dynamic Random Access Memory (SDRAM) by transferring data on both the rising and falling edges of the clock cycle. This means that while traditional SDRAM can only transfer data once per clock cycle, DDR can transfer data twice, thus offering improved performance and higher data throughput.

By utilizing this method, DDR memory became a significant advancement in memory technology, allowing for greater efficiency and speed in data processing. This innovation laid the foundation for subsequent generations of DDR memory, each improving upon the last by increasing both bandwidth and performance while maintaining power efficiency. While DDR2 and DDR3 further increased performance and bandwidth, the primary characteristic that distinguishes DDR as being specifically related to doubling bandwidth compared to traditional SDRAM is what makes it the correct choice in this context.
