Micron Technology Inc. Wednesday said it has delivered what it claimed are the industry's first samples of the next-generation GDDR3 SDRAM for graphics applications.
The Boise, Idaho, chipmaker said samples with data rates up to 6.4Gbytes/s have twice the speed of today's graphics memory, operating at about 2 watts or half the power of new DDR2 chips.
Micron shipped its first GDDR3 samples to the two leading graphics processor vendors, ATI Technologies Inc., Markham, Ontario, and Nvidia Corp., Santa Clara, Calif.
Michael Seibert, strategic marketing manager for the Micron computing and communications group, said initial production of GDDR3 is expected to begin late this year.
Seibert indicated that the JEDEC Solid State Technology Association has started drafting an industry standard for GDDR3. He expected the standard to be adopted quickly because the present GDDR3 specifications were already worked out jointly between graphics processor firms and memory suppliers.
The new GDDR3 graphics memory is an enhancement over GDDR2 now coming onto the market, Seibert said. It operates at 1.8V, compared to 2.5V for GDDR2. It has on-die termination (ODT) on both the data and command address lines, compared to ODT only on data lines for GDDR2. The GDDR3 chip also has clock rates of 600- to 800MHz, providing data rates up to 6.4Gbytes/s, and can scale higher, according to Micron.
