Interfaces Support DDR/GDDR RAM

The company's family of double data rate (DDR) memory controller interface cells provides support for DDR1 and DDR2 operating at data rates up to 800 MHz and graphics DDR, including GDDR1, GDDR2, and GDDR3 up to 1,600 MHz. The controller interface cells are full-featured, drop-in physical layer (PHY) cells that employ established technology. They also emerge as the only such components to offer an optional performance mode to support XDR DRAM, said to yield a two-to-eight times increase in system memory bandwidth. With this option, users can develop a single chip that spans multiple price/performance points depending on which memory type is in use. In addition to interfaces, the company is offering related engineering services. RAMBUS INC., Los Altos, CA. (650) 947-5000.
