    Abstract: A data processing system includes a memory controller for accessing a dynamic memory having a plurality of SIMMs that differ in size and speed of operation. The memory controller is operable in response to a request to access a given SIMM to read a SIMM definition register and dynamically produce memory access signals in accordance with the timing requirements of the particular SIMM being accessed. Such signals are set each time a SIMM is accessed. The signals provide different clock periods of RAS precharge time, RAS to CAS time, and CAS pulse width.

    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. In addition, the rate at which new associations are made is halted or reduced during the degraded backbone condition. In one embodiment, the association rate is reduced by increasing the interval between beacons transmitted by the access point which identify the access to the backbone network.
