ABSTRACT:
Unified voltage generation techniques for efficiently generating a plurality of operational voltages for use within an electronic device, such as a memory system (e.g., memory product) providing data storage, are disclosed. A voltage generation circuit can generate a regulated base output voltage. The voltage generation circuit can include one or more voltage output circuits that produce different operational voltages from the regulated base output voltage. According to one aspect of the invention, the voltage output circuits can be disabled when the different operational voltages are at their appropriate voltage potentials, thereby reducing power consumption by the voltage output circuits. The voltage generation circuit is therefore able to operate with improved power efficiency.
