Abstract:
Zone matricielle d'interconnexion universelle (605) comportant un premier ensemble de conducteurs (608-1 à 608-J) formés dans un premier sens, un second ensemble de conducteurs (609-1 à 609-K) formés dans un second sens non parallèle au premier, et une structure destinée à interconnecter électriquement certains conducteurs sélectionnés dans le premier ensemble de conducteurs (608-1 à 608-J), et un ou plusieurs conducteurs compris dans le second ensemble de conducteurs (609-1 à 609-K). Des plages de connexion (607-1,1 à 607-M,N) sont raccordées à certains conducteurs sélectionnés dans le premier ensemble de conducteurs (608-1 à 608-J) et dans le second ensemble de conducteurs (609-1 à 609-K). Certains conducteurs sélectionnés sont segmentés de manière à permettre à l'une quelconque des plages de connexion de se raccorder à une ou plusieurs autre(s) plage(s) de connexion (607-1,1 à 607-M,N) sans mettre hors fonction les plages de connexion (607-1,1 à 607-M,N) non destinées à être raccordées de cette façon.

Abstract:
A pullup circuit for use with plurality of N-Channel pulldown transistors (14a,..., 14n) connected to a bit line (12) includes a P-channel MOS pullup transistor (10) connected between the bit line (12) and a voltage rail (V DD ). An inverter (32) is connected between the bit line (12) and the drain of an N-Channel MOS transistor (34) having its gate connected to the voltage rail (V DD ) and its source connected to the gate of the P-Channel MOS pullup transistor (10). A first P-Channel MOS transistor (36) is connected between the voltage rail (V DD ) and the gate of the P-Channel MOS pullup transistor (10). A second P-Channel MOS transistor (38) having its gate connected to ground is connected between the bit line (12) and the gate of the first P-Channel MOS transistor (10). Four P-Channel MOS divider transistors (40,42,44,46) are connected between the drain of the first P-Channel MOS transistor (10) and ground. The gates of the P-Channel MOS divider transistors (40,42,44,46) are connected together to ground. The P-Channel MOS pullup transistor (10) and the N-Channel MOS pulldown transistors (14a,...,14n) are large. The first and second P-Channel MOS transistors (36,38), the first N-Channel MOS transistor (34), and the P-Channel MOS divider transistors (40,42,44,46) are close to minimum size. The P-Channel and N-Channel devices comprising the inverter devices are larger than minimum size.
Abstract:
The invention uses a programmable interconnect substrate having a plurality of conductive and interconnectable vias located on one or both surfaces thereof. A customised pattern of bonding pads is then formed over the one or both surface of the substrate which correspond to the terminal footprints of specific surface mounted packages intended to be mounted on the substrate. A generalised pattern of bonding pads may also be formed on the surface of the substrate for electrically connecting terminals of bare dice thereto by means of thin wire. All bonding pads are electrically connected to one or more vias by direct electrical contact or by a conductive trace extending from the bonding pad to a nearly via.
Abstract:
An interconnect substrate has formed thereon a first plurality of conductive leads (108-1...108-J) and a second plurality of conductive leads (109-1...109-K). A plurality of cells (106-1,1...106-J,K) are formed in the substrate, each cell having a number of bonding pads (107-1...107-M) formed on the surface of the substrate above the region of the substrate in which the cell is formed, thereby to allow a plurality of integrated circuit chips and electrical components to be attached to the substrate and electrically connected to the cells. Devices and programming elements in the substrate or in integrated circuits mounted on the substrate allow selected connections to be formed between selected ones of the conductive leads to be connected electrically thereby to allow selected components mounted on the substrate to be electrically interconnected. Other devices in the substrate or in integrated circuits mounted on the substrate allow testing of the components mounted on the substrate to determine their performance and the checking of the integrity of the connections formed between conductive leads.
