Samsung Electronics has started volume production of what it claims is that fastest DRAM memory for PCs, which offers a 33 per cent speed enhancement for image processing.

The GDDR4 (series four of graphics double-density-rate memory is fabricated on 80nm process technology and has a peak data processing rate of 2.4Gbit/s.

The 512Mbit GDDR4 memory will be offered in a 32-bit data bus configuration.

To further support high speed performance, it uses JEDEC-approved standards for signal noise reduction, including data bus inversion and multi-preamble specifications.

The high speed memory specification has been specifically developed with graphics accelerator firms such as Nvidia and ATI in mind.

According Tony Tamasi, v-p of technical marketing at Nvidia: "The graphics industry has an insatiable demand for high bandwidth memories and GDDR4 is poised to become the next major evolutionary step for our graphics processors."
 
According to Jon Peddie of the market research firm Jon Peddie Research: “Sales of high performance memory have already risen by 15% this year compared to 2005, and GDDR4 will give an even sharper boost in demand."

The firm predicted that the non-integrated graphics memory market will grow from $2.3bn in 2005 to over $4bn by the end of 2008.
