摘要:
A memory array has a plurality of rows including a plurality of memory words. Each first bit of a plurality of first bits is associated with a memory word of the each row. A state of the each first bit indicates whether the associated memory word has had an error. Each redundancy row of a plurality of redundancy rows includes a plurality of redundancy words. Each redundancy word is associated with a memory word. A corrected data cache has at least one repair word configured to store corrected data and at least one status bit associated with the at least one repair word, the status bit indicating whether the corrected data stored in the repair word is a pending repair. The corrected data cache is configured to write the corrected data stored in the repair word to at least one of a counterpart memory word or a counterpart redundancy word.

The invention relates to digital-to-analog converters for converting current. The converter includes a pair of differential branches with two transistors controlled by a digital register activated at a clock frequency, and two resistive loads receiving the currents of the differential branches to produce a differential electrical signal representing the analog result of the conversion. The converter includes a dual switching circuit for the currents of the differential branches: a first switching circuit enables the transmission of the currents of the differential branches toward the loads for 70% to 95% of the clock period and shunts these currents outside the loads for the rest of the time; a second switching circuit alternately and symmetrically makes a direct link followed by a cross link between the differential branches and the loads. The converter provides a signal with high spectral purity and can work with a good level of power in the four Nyquist zones of the spectrum of the output analog signal, and notably in the second and third zones.

A sealing film includes a first inorganic layer that has, in a surface thereof, a convex portion corresponding to an upper surface of an element layer, a second inorganic layer that covers the first inorganic layer, and an organic layer disposed between these layers. The surface of the first inorganic layer includes a recurved area changed from an area around the convex portion to the convex portion, and a flat area surrounding the element layer. The flat area includes an outer peripheral area on an outer end of the first inorganic layer, and an inner peripheral area between the outer peripheral area and the recurved area. The organic layer has an end in the outer peripheral area, has another portion in the recurved area, and avoids the inner peripheral area. A part of the second inorganic layer contacts the first inorganic layer in the inner peripheral area.

This description relates to active-pixel image sensors. Each pixel includes, at the surface of a semiconductor active layer, a photodiode region, a charge storage node and a transfer structure for transferring charges from the photodiode to the storage node after a charge integration time for charges generated by the light in the photodiode. The transfer structure includes a first transfer gate adjacent to the photodiode, a second transfer gate adjacent to the storage node, and an electron-multiplication amplifying structure located between the first and second transfer gates. The amplifying structure includes two separate accelerating gates and an intermediate diode region at a fixed surface potential, located between the two accelerating gates. A succession of alternating high and low potentials is applied to the accelerating gates while the charges are in transit in the transfer structure, before they are transferred to the storage node.

A method of forming a semiconductor device includes chemically cleaning a surface of a substrate to form a chemical oxide material on the surface. At least a portion of the chemical oxide material is removed at a removing rate of about 2 nanometer/minute (nm/min) or less. Thereafter, a gate dielectric layer is formed over the surface of the substrate.

The present disclosure provides an apparatus for manufacturing a single crystal silicon ingot having a dual crucible for silicon melting which can be reused due to a dual crucible structure. The apparatus includes a dual crucible for silicon melting, into which raw silicon is charged, a crucible heater heating the dual crucible to melt the raw silicon into molten silicon, a crucible drive unit controlling rotation and elevation of the dual crucible, and a pull-up drive unit disposed above the dual crucible and pulling up a seed crystal dipped in the molten silicon to produce a silicon ingot. The dual crucible has a container shape open at an upper side thereof, and includes a graphite crucible having an inclined surface connecting an inner bottom and an inner wall, and a quartz crucible inserted into the graphite crucible and receiving the raw silicon charged into the dual crucible.

A complementary braking system for removing liquids and solid debris from a motor vehicle's pathway and applying frictional contact in front of two or more of the motor vehicle's tires provide slowing and prevent further movement of the vehicle. The complementary braking system includes a resilient blade disposed forwardly of the motor vehicle's tires and above a road surface. The resilient blade includes an upwardly curved leading edge followed by a generally horizontal flat portion. The system also includes a pair of releasable latches that maintain the resilient blade in an elevated position until released to fall into contact with a road surface The system also includes a pair of electric motors for returning the resilient blade to an elevated latched position above the surface of the road in response to released pressure on the brake pedal.
