DDR (Double Data Rate SDRAM) is a DRAM technology that supports data transfers on both the rising and the falling edges of each clock cycle. This effectively doubles the memory chip`s data throughput and is more efficient than legacy SDR technology. PNY manufactures DDR memory upgrades rated at PC2100, PC2700, and PC3200. They are compatible with desktop and notebook computers and processors such as Intel`s Pentium, Celeron, AMD`s Athlon, Sempron and others.
