DDR SDRAM (Double Data Rate-Synchronous DRAM) is the next-generation Synchronous DRAM technology that is pushing the envelope of memory bandwidth and performance while maintaining competitive pricing. DDR is the evolutionary technology that succeeded the previous standard Synchronous DRAM technology, which is now called SDR (Single Data Rate).
