Transmeta strikes licence deal with Sony

Transmeta Corporation has licensed its LongRun2 power management and transistor leakage control system to Sony, which will use the technology to improve the battery life and performance of its notebooks and other electronic devices.

Transmeta's LongRun2 technology addresses problems associated with excessive chip heat and transistor leakage.

The technology can be used to improve semiconductor devices by reducing total chip power, reducing standby power, reducing burn-in power, improving chip performance and reducing manufacturing costs, said Transmeta.

LongRun2 follows Transmeta's first generation LongRun power management product, which allows for the dynamic adjustment of MHz and voltage hundreds of times per second, to reduce power consumption.

LongRun2 extends this technique further by using Transmeta's proprietary system of dynamically adjusting transistor threshold voltages to control transistor leakage.

This dynamic control reduces leakage caused by changes in runtime conditions, such as voltage and temperature, which are not pre-determined when the chip is manufactured.

Transmeta’s deal with Sony comes days after Transmeta said it would be re-structuring the company to concentrate on selling its technology and intellectual property, rather than manufacturing chips equipped with the technology.
