ABSTRACT:
A system includes a voltage generator to produce a pre-charge voltage signal for pre-charging one or more signals in a memory circuit. The one or more signals can be data bus lines used to access memory. The voltage generator can include an input indicating whether the memory circuit is set to a power-saving mode. The input can be used to determine whether to adjust a magnitude of the pre-charge voltage signal produced by the voltage generator. Adjusting the pre-charge voltage can result in power savings. That is, when in the power-saving mode, the voltage generator circuit can adjust the pre-charge voltage to a value that reduces an amount of leakage current associated with a pre-charge voltage. Reducing the leakage with respect to the pre-charge voltage means that the saved power can be used for other useful purposes.
