Infineon plans high-performance RAM
Even the fastest graphics processor from nVidia only works as fast as the memory allows. And this dependency has been growing lately. The outrageously expensive DDR RAM has been working on the deluxe versions for months, but its performance, for example in 32Bit at a high resolution, is no longer sufficient to supply the GPU with data.
The memory giant Infineon wants to put an end to this shortcoming for the time being and has announced the production of a 300MHz DDR RAM memory (currently max. 250MHz). One problem with this type of high-performance module, as in processor production, is the high level of scrap in the manufacturing process, which can even turn development into a loss for the manufacturer. Infineon seems to have found a way to increase production to a tolerable level, but with such high clock rates, the memory harbors another problem: the waste heat. For this reason, Infineon has dispensed with the conventional TQFP housings (side connections) and has given the memory a new BGA housing, the conductor paths of which are perpendicular between the chip and the board. This should especially intensify the dissipation of heat. Furthermore, the modules no longer run with 2.5 V, but 'only' with 1.8 V. The new memory theoretically reaches 300 MHz physically, which results in a net 600 MHz using the DDR method, an access time of only 3.3 ns. However, all of the know-how has its price. With a 64MB graphics card, the buyer will probably be able to reach 300 DM over the counter for the memory alone. Mass production is planned for the 3rd quarter of 2001.
