P.M. BRIEFING : IBM Announces ‘Fastest’ Chip

<i> From Times wire services</i>

International Business Machines Corp. said today it has produced the world’s fastest experimental million-bit memory chip at a factory in Yasu, Japan.

The dynamic random access memory chip, or DRAM, was made on an existing production line, demonstrating that it could be manufactured in large volumes, IBM said. It did not say when volume production might begin.

The chip can retrieve a unit, or bit, of information in 22 billionths of a second, making it two to three times as fast as the current generation of million-bit chips, IBM said.
