Abstract: A high security cylinder lock includes a housing comprising a plurality of driver pin bores for disposing spring loaded driver pins; a plug rotatable within the housing comprising a plurality of balancing pin bores for disposing spring loaded balancing pins and a plurality of combination pin bores for disposing combination pins. Each combination pin is sandwiched between a driver pin and a balancing pin. The extension force of the balancing spring at its pre-load length is greater than the extension force of the driver spring at its fully-load length. The compound force causes at least one combination pin partially extended into a corresponding driver pin bore in the housing when the plug is at its first rotational orientation in case of no key engaged. The key profile pushes the balancing pins to move to such position that all mating surfaces of the combination pins and the driver pins to lies onto the shear line of the lock. The balancing pin, balancing spring and balancing spring seal set may be substituted by magnetic balancing pin and magnetic seal pin set.

Abstract: A method of fabricating a flash memory integrated circuit is described. In an embodiment of the present invention a dielectric filled trench isolation region is formed in a silicon substrate. The dielectric filled trench isolation region isolates a first portion of the silicon substrate from a second portion of the silicon substrate. A portion of the dielectric in the trench is then removed to reveal a portion of the silicon substrate in the trench between the first and second portions of the silicon substrate. Ions are then implanted to form a first source region in the first portion of the silicon substrate and to form a second source region in the second portion of the silicon substrate and to form a doped region in the revealed silicon substrate in the trench wherein the doped region in the trench extends from the first doped source region to the second doped source region.

Abstract: An axial spring balancing pin tumbler lock includes a cylindrical shell, a plug rotationally disposed within the shell and rotatable by a tubular key. The shell contains a plurality of first pin bores annularly and evenly defined to the axis of the shell for receiving first pins and first springs. The plug has a through aperture for engaging with a elongated spindle, a key bore coaxially defined on front end for receiving the tubular key, a plurality of third pin bores annularly and evenly defined on front end with same depth of the key bore for receiving third pins, and a plurality of second pin bores defined on rear end of the plug for receiving second pins and second springs. Each second pin may contacts the tubular key and one of third pins simultaneously. The extension force of the second spring at its preloaded length is stronger than that of the first spring at its fully loaded length so both second pin and third pin are urged by compound extension force to their most extended position while the first pin is at its most retracted position. The extended third pins bridge the shear plane of the lock, the plug is then blocked from rotating. Since the third pins are isolated from the opening keyway and are not driven by key notches or external force directly, the conventional lock picking or bumping methods must fail.

Abstract: A memory cell including a phase-change material may have reduced leakage current. The cell may receive signals through a buried wordline in one embodiment. The buried wordline may include a sandwich of a more lightly doped N type region over a more heavily doped N type region over a less heavily doped N type region. As a result of the configuration of the N type regions forming the buried wordline, the leakage current of the buried wordline to the substrate under reverse bias conditions may be significantly reduced.

Abstract: A phase-change memory cell may be formed with a carbon-containing interfacial layer that heats a phase-change material. By forming the phase-change material in contact, in one embodiment, with the carbon containing interfacial layer, the amount of heat that may be applied to the phase-change material, at a given current and temperature, may be increased. In some embodiments, the performance of the interfacial layer at high temperatures may be improved by using a wide band gap semiconductor material such as silicon carbide.

Abstract: A planarized surface may be formed by initially forming an aperture through an insulating layer. The insulating layer and its aperture may be conformally coated with a conductive material that ultimately acts as a planarization stop. The conductive material may then be covered with another insulator that fills the remainder of the aperture. Thereafter, the structure may be planarized down to the conductive layer that acts as a planarization stop.
