  • Patent number: 7994566
    Abstract: A stacked non-volatile memory device uses amorphous silicon based thin film transistors stacked vertically. Each layer of transistors or cells is formed from a deposited a-Si channel region layer having a predetermined concentration of carbon to form a carbon rich silicon film or silicon carbide film, depending on the carbon content. The dielectric stack is formed over the channel region layer. In one embodiment, the dielectric stack is an ONO structure. The control gate is formed over the dielectric stack. This structure is repeated vertically to form the stacked structure. In one embodiment, the carbon content of the channel region layer is reduced for each subsequently formed layer.

  • Patent number: 7986623
    Abstract: A method for rejecting a request to alter a connection includes establishing a first connection with a first node and a second connection with a second node. The second connection passes through the first node and has an associated first end-to-end state. The method also includes transmitting, for relay by the first node to the second node, a first request to alter the second connection with the second node so that the second connection will have an associated second end-to-end state. The method additionally includes receiving a rejection message from the first node indicating that the first request to alter the second connection failed. The method further includes transmitting a second request to alter the second connection with the second node to ensure that the second connection is again in the associated first end-to-end state.

  • Patent number: 7979768
    Abstract: A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.
