  • Patent number: 11152046
    Abstract: A memory array that provides an internal retention voltage without a voltage regulator is disclosed. The memory array includes a first group of bit cells coupled between the power supply rail and a ground switch and a second group of bit cells coupled to a retention select circuit. The retention select circuit is coupled to the ground for the first group of bit cells and the power supply rail. The ground switch and the retention select circuit may be operated to switch the bit cells between a nominal operating voltage and a retention voltage. The retention voltage is provided during inactive periods of the memory array to maintain data in the bit cells during the inactive periods.

  • BED
    Publication number: 20210307523
    Abstract: A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.

  • Patent number: 11004482
    Abstract: Memory circuits used in computer systems may have different operating modes. In a retention mode, a voltage level of an array power supply node coupled to memory cells included in the memory circuit is reduced to a level sufficient to retain data, but not to perform read and write operations to the memory cells. A power converter circuit may be configured to generate the retention voltage level, and adjust the retention voltage level using a leakage current of dummy memory cells included in the memory circuit.

  • Patent number: 10630290
    Abstract: Computer systems may include multiple power switch circuits for coupling circuit blocks to power supply signals. Different power supply signals may be selected for use in the generation a control signal for a power switch device in the power switch circuit. For example, during a particular operating mode of a power switch circuit coupled to a circuit block, a power supply signal with a voltage level greater than an power supply signal for the circuit block may be used to generate the control signal.

  • Publication number: 20200104038
    Abstract: In some embodiments, an electronic device performs an action in response to detection of a sequence of one or more motion gestures. Motion gesture information of a first electronic device optionally includes a first portion representing a respective attitude of the first electronic device relative to a frame of reference and a second portion that includes movement of the first electronic device from the respective attitude of the first electronic device. In accordance with a determination that the movement of the first electronic device during the second portion of the motion gesture meets movement criteria for a movement gesture that corresponds to the respective attitude of the first electronic device, a process is initiated to control the first electronic device or a second electronic device in accordance with the second portion of the motion gesture.
