The long awaited super-fast DDR memory is here! DDR memory hits clock speeds up to twice as fast as standard SDRAM today! Upgrade your system with DDR memory today for brutally fast performance and speed. What is DDR Memory? DDR (double data rate) memory is the next generation SDRAM. Like SDRAM, DDR is synchronous with the system clock. The big difference between DDR and SDRAM memory is that DDR reads data on both the rising and falling edges of the clock signal. SDRAM only carries information on the rising edge of a signal. Basically this allows the DDR module to transfer data twice as fast as SDRAM. For example, instead of a data rate of 133MHz, DDR memory transfers data at 266MHzmobile users demand. Value bundled for affordability.
