The memory of type GDDR-4 did not find wide application on video cards because of its relatively high price, hardly someone has doubts that the flag graphical solutions in 2007 will begin to use GDDR-4 more actively. In last year the memory of type GDDR-4 found place in video cards Radeon x1950 XTX, where it operated at frequency 2.0 GHz DDR.
As report associates , at the conference ISSCC 2007, which will pass in the middle of February, samsung company will promulgate the characteristics of 0.08 m (80 nm) chips memory of type GDDR-4 with 512 Mbit speed, capable to work at frequency 4.0 GHz DDR. At present the most rapid series memory GDDR-4 operates at frequency 2.8 GHz DDR. The installed to one of the modifications of video card on base chip r600 use memory GDDR-4 witch operate at frequency 2.2 GHz DDR.
In order to successfully subjugate frequency 4.0 GHz DDR, the new samsung microcircuits will use a number of update, directed to save the electric power and to reduce the interferences. The appearance of more rapid chips GDDR-4 will make possible to reduce prices of the slower memory microcircuits , which will contribute to their fastest advance in the market.
