time we heard about Rambus XDR memory being used
on a wide scale was with Sony's PlayStation 3.
Nevertheless, senior vice president Sharon Holt at Rambus Licensing and
Marketing believes that "today's consumer electronics require both high
performance and superior power efficiency."
Elpida Memory in particular has shown itself
to be the top supplier of XDR RAM and continues to specialize in developing
high-performance, low-power XDR products.
Today, the Japanese company introduced the industry's first
1-Gigabit XDR DRAM based on an x32-bit configuration.
The memory features a proprietary 65nm CMOS process
designed to run at frequencies up to 7.2GHz at just 1.5v, which is faster and
more efficient than any GDDR5 memory to date.
It provides a one-chip solution that, compared with two x16-bit
configuration 512 Megabit XDR DRAMs, consumes 35-40% less power and requires
Additionally, the memory is capable of an octal data rate
and provides a data transfer rate of 28.8GB/s with a single device, making it
an ideal choice for a variety of high-bandwidth applications such as
entertainment devices with full-HD capabilities.
More specifically, the data width is x4, x8,
x16, and x32 bits programmable which is capable of delivering several times the
peak bandwidth of industry-standard DDR2-800 memory devices.
Sample shipments of the new XDR have already started and
mass production is scheduled to begin this April. Furthermore, Elpida's press release was published on January
20th and can be found here
