Title: Method of making a memory device fault tolerant using a variable domain redunancy replacement configuration
Inventor: KIRIHATA TOSHIAKI
IPC: G06F12/16
Filed: 1998-03-13
Granted: 2000-11-01
Abstract: A method of making a fault-tolerant memory device employing a variable domain redundancy replacement (VDRR) arrangement is described. The method includes the steps of: subdividing the memory into a plurality of primary memory arrays; defining a plurality of domains, at least one of the domains having at least a portion common to another domain to form an overlapped domain area, and wherein at least one of the domains overlaps portions of at least two of the primary arrays; allocating redundancy means to each of the domains to replace faults contained within each of the domains; and replacing at least one of the faults within one of the domains with the redundancy means coupled to the one domain, and at least one other fault of the one domain is replaced by the redundancy means coupled to another of the domains, if the at least one other fault is positioned within the overlapped domain area. Each redundancy unit supporting the primary memory arrays includes a plurality of redundant elements. Unlike the conventional fixed domain redundancy replacement scheme, redundancy units are assigned to at least two variable domains, wherein at least a portion of the domain is common to that of another domain. VDRR makes it possible to choose the most effective domain, and in particular, a smaller domain for repairing a random fault or a larger domain for repairing a clustered faults.

Title: Method and apparatus for maintaining a predefined transmission quality in a wireless network for a metropolitan area
Inventor: LE-NGOC THO
IPC: H04L27/00
Filed: 1998-10-14
Granted: 2000-10-11
Abstract: A technique for maintaining a predefined transmission quality in a wireless Metropolitan Area Network (MAN). Each of a plurality of Local Area Networks are coupled to a corresponding router. Each router is coupled to one or more transceivers for interconnecting the routers via wireless links. Each router stores a table representative of the topology of the MAN and receives detected indicia representative of the quality of the wireless links and representative of network traffic loads. The router adapts the manner of transmission and the path of transmission according to the indicia. As a result, the MAN is highly efficient, in terms of cost, power and bandwidth utlization. For example, a strength of a signal received over a wireless communication link is periodically monitored for maintaining the strength within a predefined range by adjusting the transmission power. In addition, an error rate for the data received over the link is monitored. If the received signal strength remains below the predefined range despite the transmit power having been adjusted to a maximum allowable level, and if the error rate approaches a predefined limit, one or more techniques are selectively employed to reduce the error rate while maintaining a sufficiently high network throughput. The adaptive techniques include changing the data rate, modulation level, error correction coding, and spectrum spreading. In addition, a path for the data is preferably selected according to an Open-Shortest-Path-First algorithm, though one or more alternate paths can be selected for transmitting at least a portion of the data.
