Abstract: Self-test architectures are provided to implement data column and row redundancy with a totally integrated self-test and repair capability in a Random Access Memory (RAM), either a Dynamic RAM (DRAM) or a Static Ram (SRAM), and are particularly applicable to compileable memories and to embedded RAM within microprocessor or logic chips. The invention uses two passes of self-test of a memory. The first pass of self-test determines the worst failing column, the column with the largest number of unique failing row addresses. After completion of the first pass of self-test, the spare column is allocated to replace the worst failing column. In the second pass of self-test, the BIST (Built In Self-Test) collects unique failing row addresses as it does today for memories with spare rows only. At the completion of the second pass of self-test, the spare rows are then allocated.

Abstract: A local word-line redundancy architecture and method that implements both word-line and match-line steering for semiconductor memories and more particularly for content-addressable memories (CAM) are introduced. According to the present invention, the method of performing local word-line redundancy comprising: testing by using BIST, storing results, comparing failing read address data and failing match-line address data to determine if redundancy is possible and, if so, storing the redundancy repair data pattern and loading that patten upon initialization so that redundancy steering is activated.

Abstract: A process and apparatus for producing laminated materials comprising a metal sheet laminated on one or both sides to a polymer film or films. The process comprises forming a laminate by a combination of heat and pressure followed by reheating. A heat zone is provided for heating and/or cooling the laminate after the reheat stage and prior to quenching so that the laminate enters the quenching stage at a substantially constant temperature, irrespective of line speed.

Abstract: An apparatus for and a method of forming a metal coated with a polymer is achieved through the provision of a reservoir containing a cooling liquid having a relative undisturbed upper surface. A metal coated with a polymer is introduced into the cooling liquid through the upper surface and is subject to quenching liquid at a temperature T.sub.q directed at the polymer coated metal substantially immediately below the cooling liquid upper surface and substantially along the entire predetermined width thereof. This achieves rapid and uniform cooling in the absence of bubble formation and/or quenching liquid surface agitation to assure desired crystalline formation of the polymer absent the polymer blemishes.

Abstract: A process for producing laminated materials in which one or more polymer films are laminated to a metal strip by a combination of heat and pressure. Generally, polymer films are applied to both sides of the metal strip in a lamination nip which exerts a force of at least 15 kN/m. The nip rolls may also be at different temperatures, either by one nip roll being of conducting material such as steel and the other nip roll being of insulating material, or by actively cooling one of the rolls. This enables films having different softening temperatures to be laminated without risk of micro-blistering or of pick-up on the rolls.
