IBM UNVEILS FASTER MEMORY CHIP

International Business Machines Corp. researchers have made the world's fastest dynamic memory computer chips, the company said at a research conference in San Francisco.

The experimental chips can retrieve a bit of information in 20 billionths of a second, three times as fast as the current generation of so-called D-RAM chips.D-RAM chips are the most common kind of memory chips in computers. They are more compact and cheaper but also slower than static random access memory chips, known as S-RAMs.

Separately, IBM said it had built an experimental S-RAM chip that can retrieve information in a record 11 billionths of a second. It announced another experimental S-RAM capable of storing 1 million bits of information, unprecedented for that kind of chip.
