Abstract
Method and device for providing voltage generation with load-based control are disclosed. The voltage generation can be provided within an electronic device, such as a memory system that provides data storage. In one embodiment, an electrical load imposed on a generated voltage can be monitored and used to dynamically control strength of the generated voltage. For example, for greater electrical loads, the generated voltage can be provided with a greater strength, and for lesser electrical loads, the generated voltage can be provided with a lesser strength. By compensating the generated voltage for the nature of the imposed electrical load, the generated voltage can be provided in a stable manner across a significant range of loads. In the case of a memory system, stability in the generated voltage provides for reduced voltage ripple and thus improved sensing margins. The voltage generation is well suited for use in portable memory products (e.g., memory cards) to generate one or more internal voltages.
