Santa Clara, Calif. Aimed at the digital consumer electronics market, Elpida Memory Inc. is sampling a 512-Mbit XDR DRAM that operates at 3.2-GHz and provides a data transfer rate of 6.4 Gbytes/s.
XDR DRAM, the memory architecture developed by Rambus Inc., is being touted as the next-generation memory for applications that require high bandwidth to support high-end graphics, digital imaging and advanced multimedia.
"Industry demand for memory bandwidth in next-generation digital consumer electronics, such as high-definition digital television and 3-D graphics applications is growing rapidly as more content becomes available and as processor performance becomes more robust," said Jun Kitano, director of technical marketing for Elpida Memory (USA).

Elpida's 512-Mbit XDR DRAM, part number ESX5116ABSE, is organized as 4M words X 16-bits X 8 banks. It is manufactured on a 0.10-micron process and available in a 104-pin FBGA package.
The device are designed with Rambus-specific features, including Differential Rambus Signal Level (DRSL) interface, which minimizes the signal swing and noise, and Octal Data Rate (ODR), which transfers 8 bits per clock cycle to achieve 3.2-GHz operation. It also features programmable on-chip termination, adaptive impedance matching, dynamic request scheduling and zero overhead refresh.
Volume production is expected in the second half of 2005. The device is sampling now for $50.
