NEWS IBM is launching a technology called Memory eXpansion (MXT) which will double the amount of memory in a computer. It is expected to be used in Intel-based servers such as IBM's NetFinity range but can also be deployed in PCs and handheld devices. The memory doubling is achieved by a chip that acts as an intermediary between the processor and the memory. The chip will be encoding the data and in order to compensate for the time it takes in encoding, it will store the data used most frequently in a cache memory, which is the memory closest to the computer's microprocessor. In practice, a typical Windows 2000 or NT server can achieve its maximum memory capacity of 168 gigabytes with only 84 gigabytes installed. Programs featuring memory compression are available already, but traditionally they use the processor to compact the data which subsequently slows down the processing. The technology is aimed at companies with a large IT installation.
