Micron is touting 256MB DDR SDRAM modules, but in industry samples only. Not that the timing has anything to do with what has been, with today's Intel Pentium 4 launch, a damn fine day for Rambus Ink.

Micron has announced availability of PC133 (said to be comparable in price with PC100 SDRAMs) and 2.5V 266MHz DDR versions. Multiple chipsets which take advantage of Micron's DDR SDRAM memory are to be introduced this quarter and next year, it says.

The 2.5V 266MB DDR part, functioning at clock rates of 133MHz, provides system-level bandwidth of 2.1GB per second. This meets the requirements of PC2100, the US memory maker points out.

Both PC133 and 266 Meg flavours are manufactured using 0.15 micron technology, which means faster speed and lower power consumption, according to Micron.

The company is planning 512MB and 1 Gig DDR DIMM modules operating at 133MHz bus speed next quarter. ®
