Aimed at the digital consumer electronics market, Elpida Memory Inc. is sampling a 512Mb XDR DRAM that operates at 3.2GHz and provides a data transfer rate of 6.4GBps.

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 3D 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).

The 512Mb XDR DRAM, part number ESX5116ABSE, is organized as 4M words x 16-bits x 8 banks. It is manufactured on a 0.10?m 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 3.2GHz 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.
