  • Patent number: 11682453
    Abstract: Devices and methods are provided for word line pulse width control for a static random access memory (SRAM) devices. A control circuit includes a first transistor, an inverter coupled to the first transistor, and a second transistor comprising a gate, a first source/drain terminal and a second source/drain terminal. The second transistor is coupled to the inverter. The first source/drain terminal of the second transistor is coupled in series to the first transistor. The second source/drain terminal is coupled to a decoder driver circuit. The second transistor is configured to charge a load of a common decoder line so as to reduce an effective load of the decoder driver circuit.

  • Patent number: 11449920
    Abstract: This disclosure describes, in part, techniques for providing add-ons associated with network applications. For instance, a user may be controlling an application that is executing on a remote system using a control device and a display device. While the application is executing, the remote system may send user interface data to the display device, where the user interface data represents a user interface that includes add-ons that may be acquired for the application. If the user selects an add-on, the display device may communicate with a payment system in order to acquire the add-on. The remote system may then determine that the user acquired the add-on using data received from the display device and/or data received from a management system associated with the application. As such, the remote system may enable the add-on for the user within the application.

  • Patent number: 10658026
    Abstract: Devices and methods are provided for word line pulse width control for a static random access memory (SRAM) devices. An inverter within a pre-decoder circuit receives a first input of a clocked address. The inverter determines an output based on the clocked address. An electrical load of a decoder driver circuit of the SRAM device is modified based on the output. Current to a transistor coupled at a common node is provided. The transistor is configured to electrically couple a plurality of transistors of the decoder driver circuit within the SRAM device.
