O que significa a palavra leakage?

Uma empresa de processadores criou um mecânismo inteligente de hardware que faz o ajuste dinâmico de leakage dos transistores.

Abaixo segue o texto original sobre esse mecânismo:
Transmeta's second generation LongRun2 technology extends this approach further. It now allows dynamic adjustment of transistor leakage. Dynamic control is important in order to adjust leakage due to changes in runtime conditions, such as voltage and temperature, that are not predetermined when the chip is manufactured.
