  • Publication number: 20200118602
    Abstract: A power switch control circuit includes a supply rail configured to supply power to a memory array. A first header switch couples the supply rail to a first power supply that corresponds to a first power domain. A second header switch couples the supply rail to a second power supply that corresponds to a second power domain. A control circuit is configured to receive a select signal and a shutdown signal, and to output control signals to the first and second header switches to selectively couple the first and second header switches to the first and second power supplies, respectively, in response to the select signal and the shutdown signal. The control circuit is configured to output the control signals to the first and second header switches to disconnect both the first and second header switches from the first and second power supplies in response to the shutdown signal and irrespective of the select signal.

  • Publication number: 20200081636
    Abstract: Various embodiments for configurable memory storage systems are disclosed. The configurable memory storages selectively choose an operational voltage signal from among multiple operational voltage signals to dynamically control various operational parameters. For example, the configurable memory storages selectively choose a maximum operational voltage signal from among the multiple operational voltage signals to maximize read/write speed. As another example, the configurable memory storages selectively choose a minimum operational voltage signal from among the multiple operational voltage signals to minimize power consumption.

  • Patent number: 10276232
    Abstract: A sense amplify enable (SAE) signal is generated on a SAE line by receiving a trigger signal at a first circuit portion coupled to a first domain power supply and a second circuit portion coupled to a second domain power supply. The second domain power supply is separate and distinct from the first domain power supply. The first circuit portion and the second circuit portion are each further coupled to the SAE line for carrying the SAE signal. For a first period of time, a first portion of the SAE signal is generated based on the first domain power supply using the first circuit portion. And, for second period of time, a second portion of the SAE signal is generated based on the second domain power supply using a second circuit portion.

  • Patent number: 9659603
    Abstract: A power management circuit for an electronic device sequentially activates and/or deactivates electronic circuits of the electronic device. The power management circuit provides a first group of one or more circuit power management signals to activate and/or deactivate a first electronic circuit from among the electronic circuits. Thereafter, the power management circuit provides a corresponding power management signal from among a second group of the one or more circuit power management signals that corresponds to a portion of the first electronic circuit that has been activated and/or deactivated by the first group of the one or more circuit power management signals to activate and/or deactivate a portion of a second electronic circuit from among the electronic circuits. The power management circuit continues to sequentially provide each of the one or more circuit power management signals in a similar manner until the electronic circuits of the electronic device have been activated and/or deactivated.
