The invention discloses a method and an apparatus for creating an elementary optical disc master with but a single layer to be applied to a disc substrate to form pits having ideal shapes and without berm buildup. These ideally shaped pits are improvements in the technology of disc mastering, due to the manufacturing and data playback advantages that are inherent in the ideally shaped pits. An optically active lamina consisting of a dye polymer solution of nitrocellulose and a increased dye additive is spin coated directly to a pregrooved polycarbonate substrate to enable the recording of data on the disc by laser means in the form of pits. The pits are created by having a data modulated laser focusing on the optically active lamina which reacts to the irradiation causing a pit to be formed. The resulting pit more often than not possesses a residual raised berm area surrounding the pit, in what is considered to be a less than ideal shape for a pit. The residual berm, however, is eliminated by an additional process and step of passing the recently recorded disc under a UV illumination source before application of a final conductive layer to the disc.

As memory geometries continue to scale down, current density of magnetic tunnel junctions (MTJs) make conventional low current reading scheme problematic with regard to performance and reliability. A body-voltage sense circuit (BVSC) short pulse reading (SPR) circuit is described using body connected load transistors and a novel sensing circuit with second stage amplifier which allows for very short read pulses providing much higher read margins, less sensing time, and shorter sensing current pulses. Simulation results (using 65-nm CMOS model SPICE simulations) show that our technique can achieve 550 mV of read margin at 1 ns performance under a 1V supply voltage, which is greater than reference designs achieve at 5 ns performance.

The present invention belongs to the computer vision field and relates to a gray projection-based license plate character segmentation method. According to the specific problem of license plate character segmentation, the objective of the invention is to improve the accuracy and reliability of license plate character segmentation and satisfy a requirement for real-time performance. The method includes the following two steps of: 1, removing the license plate borders of an input license plate area image: the upper border and lower border of a license plate are removed, and the left border and right border of the license plate are removed; and 2, segmenting license plate characters. With the method of the invention adopted, difficulties caused by complicated picture background, the influence of whether and illumination, the burring of license plate regions of the license plates of old vehicles and the license plates of illegal vehicles, and the like in an image processing process can be effectively eliminated, and therefore, the high reliability of the reading of license plate characters is high, the recognition of the license plate characters is high, robustness is good, step calculation is simple, high efficiency can be maintained, a requirement for real-time performance can be satisfied, the accuracy of the license plate recognition of a monitoring system is improved, and road traffic and parking lot vehicle management can be greatly promoted.

A method for operating a non-volatile memory device which includes a plurality of memory cells serially coupled between a source selection transistor and a drain selection transistor, a first dummy memory cell coupled between the source selection transistor and the memory cells, and a second dummy memory cell coupled between the drain selection transistor and the memory cells includes applying a verification voltage to a gate of a selected memory cell, applying a first voltage to gates of unselected memory cells, and applying a second voltage that is lower than the first voltage to a gate of at least one of the first dummy memory cell and the second dummy memory cell, during a program verification operation.

A read process is performed on an ith designated block storing an ith divided data string. If the ith divided data string is not normally read, the read process is sequentially executed on ith ordinary blocks each storing the ith divided data string, where the ith ordinary blocks are included in ordinary block groups, respectively. When the ith divided data string is normally read, it is determined whether or not reading p divided data strings has been completed. If it is determined that the reading the p divided data strings has not been completed, the read process is performed on an (i+1)th designated block storing an (i+1)th divided data string following the ith divided data string.
