IBM claims to double PC memory

IBM last week announced a chip technology that it said can effectively double the memory in a PC server.

Called Memory Expansion Technology (MXT), the new memory-controller chip will reside between the processor and the main memory on a server's motherboard.

The most frequently accessed data is stored on the controller chip for rapid transmission. The controller chip sends data that is used less frequently to the computer's memory, rather than to a slower-performing disk as in current server architectures.

IBM's research division claimed that MXT has the ability to double the memory of the standard PC-based on Intel technology.

The first servers to use the new technology should be available by early next year, IBM said.

The company also said that data stored by the device can be decompressed in nanoseconds.

To make it work, Big Blue adapted an available serial-processing algorithm that can be built directly into the chip, said Ellen Yoffa, IBM's director of personal and scalable systems research.

"Others have tried to boost memory in the past, but the reason they failed where we succeeded is [that] they attempted to do this using software," she said.
