PC333 memory production to begin in September

Memory chip makers are expected to begin mass production of PC333 DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory) in September, said Alex Wu, director of integrated products at Silicon Integrated System Corp. (SIS), in an interview here at the CeBIT Asia exhibition.

"It (PC333) is already available. We already have samples," Wu said.

The announcement that PC333 will soon enter volume production comes as SIS readies the launch of its 645 DDR chip set for Intel's Pentium 4 processor. The 645 is expected to be the first DDR chip set which will support PC333 memory for the Pentium 4. Rival chip-set maker Via Technologies Inc. also plans to launch a DDR chip set soon for the Pentium 4, the Apollo P4X266, but its chip set does not support currently support PC333.

Intel has plans to introduce a version of its 845 chip set that supports DDR in early 2002.

Offering throughput of nearly 2.7G bytes per second, PC333 DDR memory is substantially faster than PC266 DDR memory, which has a throughput of around 2.1G bytes per second. By comparison, RDRAM (Rambus DRAM) offers throughput of around 1.6G bytes per second.

CeBIT Asia runs through Saturday.
