  • Patent number: 9837144
    Abstract: A memory circuit includes a set of subarrays of memory cells and a set of write assist circuits for generating negative voltages on bitlines pertaining to the set of subarrays, respectively. A set of distinct signals initiate the write assist circuits in generating the negative voltages for subarrays, respectively. The distinct signals may have particular state to cause a subset of the write assist circuits to generate the negative voltages if the corresponding subarrays are target of a writing operation, and another state to cause another subset of the write assist circuits to not generate the negative voltages if the corresponding subarrays are not target of the writing operation. This avoids the unnecessary generation of negative voltages for subarrays that are not the target of a writing operation so as to reduce power consumption. The generation of the distinct signals may be based on a set of write mask signals.

  • Patent number: 9467458
    Abstract: In one embodiment, a method includes, by a computing device, receiving identifiers of one or more sessions, users, or groups selected to have access to a particular redirected device. The computing device stores the identifiers in a database, receives a request associated with a session, user, or group to access the particular redirected device, and determines whether an identifier for the session, user, or group associated with the request is stored in the database. If the identifier is stored in the database, then the computing device grants access to the redirected device, or if the identifier is not stored in the database, then the computing device blocks the session, user, or group from accessing the redirected device.
