Thunderbird will have inexpensive 3.2GB/sec ram, using a single channel, that matches the data rate of the Athlon back end bus by Q3. The dual rambus channels on Intel's 840 chipset would provide 3.2 GB/sec (if the chipset worked and anyone could find or afford the RDRAM for it). Athlon will have the same bandwidth, with lower latency, at a 5 to 10% premium over PC100.

Micron samples 150MHz, 166MHz 2Mb x32 DDR SDRAMs
Mar 23, 2000 --- Micron Technology today began samping 2 Mbit x 32 double data rate (DDR) synchronous DRAMs (SDRAMs) at 150MHz and 166MHz speed grades.
The same DDR SDRAMs will be available at 183MHz and 200MHz speed grades in the third quarter of this year, the firm said.
Fabricated on Micron's advanced 0.18-micron process technology, Micron is targeting the chips at high-bandwidth memory applications such as high-end graphics, networking and telecommunications customers.
The chips are offered in a standard 100-pin TQFP packages. The 150MHz version carries a part number MT46V2M32LG-65, while the 166MHz version is part number MT46V2M32LG-6. Data sheets are available. Pricing will be comparable to 2 Mbit x 32 SDRAMs, Micron said. Both parts are expected to be available in production volumes in the second calendar quarter of 2000. The memory giant said 4 Mbit x 16 DDR SDRAM devices will be available in the third calendar quarter.
Micron's specialty DRAM portfolio now includes 150MHz and 166MHz 2 Mbit x 32 DDR SDRAMs, 143MHz and 166MHz 2 Mbit x 32 SDRAMs, and 143MHz and 166MHz 1 Mbit x 16 SDRAMs.
"We expect demand for the 1 Meg x16 SDRAM and 2 Meg x 32 SDRAM to remain strong through 2000, with demand shifting to the DDR devices in the second half," said Gary Welch, Micron's marketing manager for specialty memories. |
