  • Patent number: 10607662
    Abstract: A Static Random Access Memory (SRAM) array power supply circuit is presented. The circuit comprises an SRAM test unit having a substantially same structure as a basic SRAM unit in the SRAM array; a switch device connected to a power source, the SRAM test unit, and the SRAM array; and a switch control circuit connected to the SRAM test unit and the switch device. When a test voltage in the SRAM test unit is lower than a threshold voltage, the switch device is closed so that the power source begins to charge the SRAM array and the SRAM test unit. The SRAM test unit provides an early warning for the SRAM array, allowing the latter to be charged upon fulfillment of a condition (e.g., charge is low). Compared to conventional circuits, this circuit provides an output voltage that is more stable and less susceptible to the changes in external conditions such as temperature or pressure.

  • Patent number: 9861623
    Abstract: The present invention provides methods for treatment of a RAS-positive disease, in particular KRAS-positive non-small cell lung cancer as well as a method for potentiating the apoptotic activity of a PDE? inhibitor by combining the PDE? inhibitor with a direct autophagy inhibitor. The PDE? inhibitor is preferably, but not exclusively, deltarasin, and the direct autophagy inhibitor is in particular 3-methyladenine. Further provided by the present invention are a kit and a pharmaceutical composition comprising the PDE? inhibitor and a direct autophagy inhibitor. The methods of the present invention in particular provide a new treatment option for RAS-positive diseases such as KRAS-positive non-small cell lung cancer allowing for an increased apoptotic activity of the PDE? inhibitor by simultaneously blocking its “tumor protective” autophagy.
