direct rambus DRAM (DRDRAM)

The Rambus memory device with dynamic random access (DRDRAM) is characterized by extremely high clock rates and data transfer rates. With a clock rate of 800 MHz and a 16-bit bus, maximum data transfer rates of 1.6 GB/s are achieved. The DRDRAM, which is characterized by a new RAM architecture, has 184 contacts and operates at 2.5 V (2V5).

DRDRAMs are also referred to as PC800, based on the doubling of the bus clock from the Pentium 4 with 400 MHz.
