  • Patent number: 8730739
    Abstract: A semiconductor device and a method for accelerating erase verification process thereof are introduced, in which a correction unit of erase verification is connected between broken bit lines of the semiconductor device and a page buffer. Grounding switches in the correction unit of erase verification are allowed to connect the broken bit lines to ground during an erase verification process by means of a specific circuit arrangement with respect to the broken lines. Thereby, the earth voltage is received, and further, that the broken bit lines pass the erase verification is identified by the page buffer, further saving time consumed in repeated verifications in the conventional technology significantly.

  • Publication number: 20140056088
    Abstract: A method of identifying a damaged bitline address in a non-volatile memory device is introduced. The non-volatile memory device includes a memory cell array and a plurality of bit lines crossing the memory cell array. Each bit line has a first end and a second end. The bit lines are divided into a first group and a second group. The method includes applying a source voltage (charging) or ground voltage (discharging) to a specific group of bit lines, testing the bit lines in two testing stages (open-circuit testing and short-circuit testing) by the principle that no damaged bit line can be charged or discharged, and acquiring an address data of a damaged bit line according to a status data stored in a page buffering circuit and related to whether a bit line is damaged, thereby dispensing with a calculation process for estimating the address of the damaged bit line.

  • Patent number: 8578460
    Abstract: Technologies are generally described for automatically reconnecting a security principal to cloud services through correlation of security principal identifier attributes. A new security principal for a user may be detected and automatically reconnected to the user's cloud based services. An administrator for the security domains may specify a value of a unique security principal metadata attribute for the original security principal in a customizable security principal metadata attribute in the new security principal in the same or new security domain. A secondary verification metadata attribute may optionally be specified to ensure the correct security principal is reconnected to the user's cloud based resources. The correlation between the original security principal for the user and the new security principal may be used to reconnect the user's cloud resources.

  • Patent number: 8553706
    Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator is configurable to transmit a beacon at an interval based on a phase of a powerline cycle. The interval of the beacon can be substantially equal to two periods of the powerline cycle. The interval of the beacon includes a reserved region including a persistent allocation region and a non-persistent allocation region. The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period. The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.

  • Patent number: 8537629
    Abstract: A method of testing bitlines in a non-volatile memory device is introduced. The non-volatile memory device includes a memory cell array and a plurality of bitlines crossing the memory cell array. Each of the bitlines has a first end and a second end. The bitlines are divided into a first group and a second group. The testing method includes applying a supply voltage (for charging) or a ground voltage (for discharging) to a specific group of bitlines. The bitlines are tested in two testing stages, namely an open-circuit bitline test and a short-circuit bitline test, based on the feature that a defective bitline cannot be charged or discharged. The open-circuit bitline test and the short-circuit bitline test are quick and dispense with a lengthy programmed/erasing process.

  • Patent number: 8027332
    Abstract: Call routing to user communication devices is facilitated. According to an example embodiment, a call-routing switch arrangement uses data in a programmable database to associate or match incoming calls with destination user-communication devices for users employing two or more user identifiers. The incoming calls are then routed to the destination user-communication devices in response to the match. In some applications, the user identifiers include local and virtual telephone numbers for a particular user, the local number pertaining to a geographical location relating to the user's communication device or to a service via which the user's communication device is connected (e.g., a mobile telephone service), and the virtual telephone number to a different geographical location.

  • Patent number: 7684554
    Abstract: The present invention is directed to a method and system for routing communications. A plurality of communication devices are coupled to a communications network. Each communication device has a device identifier. A user-programmable database associates each of a plurality of user identifiers with a device identifier. A call-routing switch arrangement is coupled to the communication network through a portal communication device having a portal identifier. A user designates a destination user identifier when making a communication. The call-routing switches the call, directing the call to a destination device identifier responsive to the user-programmable database association between the destination user identifier and a device identifier. According to the present invention, communications are directed to users and are routed to associated equipment, a user identifier serving as a virtual extension number.

  • Publication number: 20040205458
    Abstract: As millions of computers sold every year into the consumer and corporate market and over hundreds of millions of PCs connected to the Internet, whose users and exchanged data grew by orders of magnitude in last 5 years. Even though traditional telephone and mobile phone will still provide effective point-to-point audio-only communications, it will be PCs (desktops and laptops) and handheld devices in the near future that provide real-time multipoint multimedia communication over the emerging IP network. In addition to the exchange of audio/video and textchat data from distance sites, more and more services allow joint viewing and annotating of documents, which bear different kinds of formats varying from PowerPoint, Word, Excel, Postscript, Text, and various image formats (bitmap, gif, and jpeg). This calls for a new development effort by HomeMeeting to design and implement a new unified document converter for real-time meeting/conferencing applications.

  • Patent number: 4711451
    Abstract: A reel mapping scheme which allows one standard reel stop control software routine to control the stopping of the reels when the device is operated as a standard gaming device, a multiple stop gaming device or a virtual reel gaming device. The gaming device includes a number of rotating symbol bearing reels, each reel having n stop positions associated with each symbol on the reel. For each reel, the gaming device stores a map of the symbols on the reel in a symbol map memory and a map of the stop positions on the reel in a stop map memory where the data stored in the first location in the reel map memory represents the first stop for a symbol whose data is stored in the first location in the symbol map memory. Three mapping indexes are stored for each reel. One index stores only one value representing an address offset to the reel map memory at one location for each symbol on the reel to provide a standard gaming device.
