An IP (Internet Protocol) session for a mobile node is carried out through the use of a virtual care-of address. A foreign agent sends an agent advertisement to the mobile node to allow the mobile node to choose from a list of IP addresses of the foreign agent. The foreign agent ties a virtual care-of address to a mobile node so that an intelligent and dynamic selection of tunnels to be used for the IP session can occur. Therefore, traffic for an IP session is not limited to transmission over the single particular tunnel that corresponds to an IP address initially selected by the mobile node. Rather, the virtual care-of address shifts the tunneling decision from the mobile node to the foreign agent. Supporting multiple tunnels between home agent and foreign agent allows resilience, redundancy, and service-level differentiation to mobile node traffic without involving the mobile node in the process.

A data bit to be stored in a defective cell having a logic state that is complementary to the biased logic state of the cell results in the program data being inverted and programmed. An inversion status bit is programmed to indicate the inverted status of the programmed data. During read out, the inversion status bit causes the stored data to be re-inverted into its original program data states.
