Hyundai Electronics Industries has introduced a 64Mbit 166MHz double-data-rate SDRAM for dedicated graphics chipset memory.
The DDR chip has a data transfer rate of 333Mbps and can be linked together to achieve a bandwidth of 5.3GB per second, far exceeding conventional SDRAM graphics memory which achieves typical bandwidth of 2.7 to 3.2-GB per second, company officials said.
Because of the greater throughput available with the double-clocked SDRAM, Hyundai and several other suppliers are projecting that DDR SDRAM will replace single-data-rate memory chips next year as the preferred choice for graphics frame buffers.
Full production of the chip is expected in August, at a unit price of about $14.
