Default IBM Details Memory Advance for Chips

Fox News (yes I said Fox News) reports on this 'major advance' in memory technology.

"SAN JOSE, Calif. IBM has devised a way to triple the amount of memory stored on computer chips and double the performance of data-hungry processors by replacing a problematic type of memory with a variety that uses much less space on the slice of silicon.

International Business Machines Corp. said Wednesday that its new memory technology will help unclog crippling bottlenecks that build up as increasingly powerful microprocessors attempt to retrieve data from a separate memory chip faster than it can be delivered.

"We kill ourselves in the semiconductor industry to try to get a little bit more performance in each generation. What we're doing here is trying to merge two technologies ... on the same chip to get significantly more memory," said Lisa Su, vice president for semiconductor research and development at IBM.

Armonk, N.Y.-based IBM said its solution entails swapping out most of the static random access memory, or SRAM, used to store information directly on computer chips and integrating onto the chip another kind of memory, known as dynamic random access memory, or DRAM.

SRAM is a type of memory that's fast and easy to manufacture but takes up a lot of valuable real estate on the chips. DRAM, the most common type of memory used in personal computers, has typically been stored on a separate chip and has previously been viewed as too slow to be integrated directly onto the microprocessor."
