Inventor: BUI CHI D
IPC: G11C11/41
Filed: 1998-02-13
Abstract: A method and device for selectively writing to portions of a memory word which is cleared during the write operation. Information from all of the bytes in a memory word are stored in a temporary space (a cache) prior to clearing the memory word, and thereafter, a portion of the stored information is written to at least one of the bytes in the memory word, and new information is written to at least one other byte in the memory word. The writing steps are accomplished using at least one multiplexer which selectively writes either stored information or new information in response to a control signal from the processor. The temporary space (cache) includes a latch for each memory cell, and the multiplexer includes an enable line having on and off states, such that the multiplexer writes information stored in a latch to the memory word if the enable line is in its off state, but writes new information to the memory word if the enable line is in its on state. The memory word can be one of a plurality of memory words in the memory device (RAM), and the memory word is accessed using an addressable word line.

Patent CA-2252800-A1 (CA)
Inventor: JOHNSON DAVID
IPC: H04L12/701
Filed: 1997-04-23
Abstract: Communication traffic is allocated through a network of interconnected nodes (103). A communication path may be established between terminals (101) via a plurality of routes. Parameters are processed for portions of a set of potential routes to determine a notional cost of using each of these routes. An optimal level of traffic is identified for each route portion and a parameter (such as notional route length) is adjusted to make the use of said route more costly if the traffic for that portion exceeds said notional value and, in addition, if said traffic for said portion falls below said optimum value. A route is then selected with reference to route cost comparisons.
