Abstract: Maximized multi-state compaction and more tolerance in memory state behavior is achieved through a flexible, self-consistent and self-adapting mode of detection, covering a wide dynamic range. For high density multi-state encoding, this approach borders on full analog treatment, dictating analog techniques including A to D type conversion to reconstruct and process the data. In accordance with the teachings of this invention, the memory array is read with high fidelity, not to provide actual final digital data, but rather to provide raw data accurately reflecting the analog storage state, which information is sent to a memory controller for analysis and detection of the actual final digital data.

Abstract: Nonvolatile memory cell and process in which a thin floating gate is formed with a rounded lateral edge and a thickness on the order of 100-1000 Å over a gate oxide in an active area on a silicon substrate. A tunnel oxide is formed adjacent to the rounded edge of the floating gate, and a control gate is formed with a lower portion next to the tunnel oxide and an upper portion overlying the floating gate. In some disclosed embodiments, the upper portion of the control gate completely overlies the floating gate, and in others it only partially overlies it.

Abstract: A microprocessor with reduced context switching overhead and a corresponding method is disclosed. The microprocessor comprises a working register file that comprises dirty bit registers and working registers. The working registers including one or more corresponding working registers for each of the dirty bit registers. The microprocessor also comprises a decoder unit that is configured to decode an instruction that has a dirty bit register field specifying a selected dirty bit register of the dirty bit registers. The decoder unit is configured to generate decode signals in response. Furthermore, the working register file is configured to cause the selected dirty bit register to store a new dirty bit in response to the decode signals. The new dirty bit indicates that each operand stored by the one or more corresponding working registers is inactive and no longer needs to be saved to memory if a new context switch occurs.

Abstract: A continuous flighted conveyorbelt (18) is fed product (12) from a transverse direction. As the belt moves the product forward, offset water jets (56) cause some of the items not seated in a flight (20) to be rotated and captured in the flights. Further movement brings the product (12) to a zone where water jets (72) force all items to one side against a registration plate (76). Excess product and items not captured are forced off the surface of the belt by water jets (62) and are carried away to be fed again. A cutting blade (84) is set an appropriate distance from the registration plate (76) to trim product captured and registered. The products are then forced across the width of the belt by repositioning water jets 102 and stop against a second registration plate (104). A belt (82) covering the top of the belt flights (22) prevents items from escaping through the top of the conveyor.

Abstract: Direct writing method and apparatus and methods for imaging charged toner particles directly to a print receiving medium. The charged toner particles are imaged directly to a print receiving medium using one electronic writing head for each color. The writing heads employ voltage traveling waves to convey toner in the form of toner packets to toner transport channels. The size of the toner packets is controlled by using additive or subtractive methods to perform imaging.

Abstract: A technique for immobilizing biological molecules, in particular nucleic acid strands, is described. Biological molecules immobilized at surfaces can be used in electron-transfer detection techniques in which a binding partner of a biological molecule is brought into proximity of the surface-immobilized biological molecule, an electrical potential created between the two biologically-binding species, and electron transfer through the species determined. Another technique involves immobilizing a bioligical molecule such as a protein, DNA, etc. at a surface via a self-assembled monolayer, affecting the biological molecule via, for example, biological binding, inducing a change in conformation via a prion, etc., and detecting an electronic property change in the molecule via a change in inpedence associated with an electronic circuit addressed by the biological molecule. These technique facilitates combinatorial array detection articles.

Abstract: A flash memory circuit includes a word line decoder with even and odd word line latches and a source line decoder with a source line latch. The word line decoders and the source line decoder provide the capability of erasing the memory cells of two adjacent word lines in a flash memory simultaneously and a verifying the memory cells word line by word line. By erasing two adjacent rows simultaneously, the embodiments of this invention eliminate over-erasure and source disturbance problems associated with conventional flash memory circuits. The decoding architecture provides flexible erase size that may be from a pair to a large number of multiple pairs of word lines. By dividing the memory cells of a word line into a number of segments and having segmented source lines controlled by source segment control lines and transistors, the decoding circuit further provides the capability of selecting the memory cells of a word line segment for erasing.
