A method and apparatus for transferring a signal from a high voltage, low current source to a word select line in an electrically erasable, programmable read-only memory wherein a control signal is generated which is incremented in magnitude over time, the control signal being used to control a signal path between the high voltage, low current source and the desired word select line, such that the signal path is established whenever the difference between the control signal and the signal level on the word select line exceeds a predetermined threshold level, whereby the signal level on the desired word select line increases gradually over time to the high voltage level.

A charge pump for providing programming voltages to the word lines of a semiconductor memory array is disclosed. The charge pump, configured as a combination of enhancement and native MOS transistors, prevents DC current from flowing from the source of the programming voltage to ground through unselected word lines, and thereby permits the design of semiconductor programmable memory arrays having on-chip programming voltage generation, allowing for design of semiconductor programmable memory arrays which operate from a single voltage power supply.

The present invention provides a modular system for at least one of displaying and storing at least one article. The modular system includes at least a pair of elongated support brackets having magnetic protrusions; at least one elongated cross member having downwardly facing end stops and means for positioning each of the at least one elongated cross member and the at least said pair of elongated support brackets in a generally horizontal plane during use of the modular system. The at least a pair of elongated support brackets are disposed in a spaced apart parallel relationship with each other. The at least one elongated cross member is sized to at least span a distance between the at least pair of elongated support brackets. Additionally, the at least one elongated cross member may at least rest on a top edge of each of the at least the pair of elongated support brackets during use of said modular system.

A page buffer for a NAND memory array has a data register and a cache register that are suitably organized and operated to eliminate gaps and discontinuities in the output data during a continuous page read. The cache register may be organized in two portions, and the page data in the cache may be output from the cache portions in alternation. ECC delay may be eliminated from the output by performing the ECC computation on one cache portion while the other is being output. The data register may also be organized in two portions corresponding to the cache portions, so that data may be transferred to one cache portion while the other is being output. In a variation, the continuous page read may be done without ECC.

Systems, methods, and devices are provided for an adaptive wireless network. A wireless network device for an adaptive wireless network can include an application specific integrated circuit (ASIC) including logic and memory resources coupled to the ASIC. The logic can store information received from a number of clients associated with the wireless network device regarding capabilities of the number of clients in the memory resources. The logic can adapt a guard interval and/or a channel width for transmission of a data stream according to capabilities of a number of clients associated with the wireless network device.

To enable a network apparatus to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside an L2 bridge forwarding table in the network apparatus. As a client moves from a subnet associated with a first network element to a subnet associated with the network apparatus, a determination is made regarding whether the client is roaming by evaluating a source IP address within a L3 packet header within a first frame received at the network apparatus. If, as a result of the evaluating step, it is determined that the client is roaming, the L2 bridge forwarding table is configured to include a source MAC address of the client together with information identifying a destination interface for use in directing client data traffic back towards the subnet associated with the first network element.

To enable devices to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside a bridge in a non-intrusive way. In particular, as a client moves from a subnet associated with a first network element to a subnet associated with a second network element, a determination is made regarding whether the client is roaming. This is done by evaluating a source IP address within a L3 packet header within a first frame received at the second network element. If, as a result of the evaluating step, it is determined that the client is roaming, an L2 bridge forwarding table in the second network element is configured to include a source MAC address of the client together with information identifying at least a destination interface for use in directing client data traffic back towards the subnet associated with the first network element. The first frame is then forwarded. In one embodiment, the traffic is directed back towards the subnet associated with the first network element via a GRE encapsulation tunnel, although any convenient tunneling mechanism can be used. According to another feature, given information cached at the foreign access point is used to enable the roaming client to continue to seamlessly receive inbound traffic prior to or during the configuration of the L2 bridge forwarding table (i.e., before any outbound traffic is actually sent from the client).

A fast roaming (handoff) service is provided for a WLAN infrastructure. A given mobile station (STA) obtains a pairwise master key (PMK) when it associates with an access point (AP) in the infrastructure. A neighbor graph identifies prospective APs to which the STA may then roam. At initialization, preferably the neighbor graph is fully-connected (i.e., each AP is assumed to be connected to every other AP). The PMK (obtained by the STA initially) is shared proactively with the neighbor APs as indicated in the neighbor graph. Thus, when the STA roams to a neighbor AP, because the PMK is already available, there is no requirement that the STA initiate a real-time request to an authentication server to re-associate to the new AP. Further, the new AP causes an update to the neighbor graph information implicitly by simply issuing a notification that it is now handling the STA that arrived from the prior AP; in this manner, the prior AP is confirmed as a neighbor, but there is no requirement for any inter-AP dialog before a given neighbor graph is updated. As roaming occurs the neighbor graph is pruned down (to reflect the actual neighbor AP connections) using the implicit notification data.
