DRAM which adopts the high-speed interface technology Direct Rambus which the Rambus corporation developed. As for bus width 8 bits. 800MHz (400MHz DDR) with to operate at very high clock frequency, as for maximum transfer rate 1.6GB/s. It is memory standard of the next generation who improves RDRAM transfer rate 600 - 700MB/s.

At the beginning it was expected as the memory for the personal computer which is substituted to SDRAM with the extensive backup of the Intel corporation, but spread is late from the fact that among other things you could announce the trouble of chip set of the Intel corporation which corresponds to lag of the price price decline with the fact that production volume is small and dispute and Direct RDRAM which go round the intellectual property right of the Rambus corporation and major memory manufacturer each company largely.
