Abstract:
In one aspect, a non-volatile memory device is provided which is operable in a programming mode and a read mode. The memory device includes a memory cell array which includes a plurality of non-volatile memory cells, a plurality of word lines, and a plurality of bit lines. The memory device further includes an internal data output line for outputting data read from the bit lines of the memory array, and a page buffer operatively connected between a bit line of the memory cell array and the internal data output line. The page buffer includes a sense node which is selectively connected to the bit line, a latch circuit having a latch node which is selectively connected to the sense node, a latch input path which sets a logic voltage of the latch node in the programming mode and the read mode, and a latch output path which is separate from the latch input path and which sets as logic voltage of the internal date output line according to the logic voltage of the latch node.
Abstract:
A nonvolatile semiconductor memory device has a special test mode and circuitry for counting its own fail bits. During the test mode, test data is stored in the memory, and also in a special expected data buffer. The test data stored in the memory cells are then compared to that stored in the expected data buffer. Where there is no correspondence, fail bits are detected. The lack of correspondence is registered, counted, and output to a data output buffer block.
Abstract:
A molding apparatus for molding semiconductor devices using a molding compound in which a mold is automatically treated with a mold releasing agent is provided. A lead frame strip in-magazine part and a tablet loading part are designed so that dummy lead frame strips and releasing tablets used in a mold releasing agent treatment process are automatically supplied to the molding apparatus in a mold releasing agent treatment mode or a mold cleaning mode. After the mold releasing agent treatment mode or mold cleaning mode is complete, the molding apparatus is switched back to a normal molding process and normal lead frame strips and molding compound tablets are to the mold part. In addition, a pick-up part and a stack magazine part are designed to distinguish by-products generated during the mold releasing agent treatment process from normally molded products by switching from a normal molding process to either a mold releasing agent treatment process or a mold cleaning process.
Abstract:
A semiconductor memory device including an array with a first memory cell block having redundancy blocks and a second memory cell block having normal blocks. A redundancy block in the first memory cell block is substituted for a defective normal block in the second memory cell block. The substitution is performed by a block selection circuit. When substitution is required, the block selection circuit selects from among the first memory cell blocks in inverse order, beginning with the first memory cell block having the highest address. First memory cell blocks that are not substituted for defective cell blocks are used as normal memory cell blocks by the block selection circuit.
Abstract:
A method for forming a defective pad repair structure in a liquid crystal display device having a plurality of pads disposed on a substrate. At least one defective pad repair line is provided to oppose the pads with an insulating layer disposed between the pads and the defective pad repair line. When at least one of the pads is broken, the broken pad can be restored by connecting the broken pad to the repair line by a welding process.

Abstract:
A pyroelectric infrared radiation detector is capable of removing internal noise generated in a pyroelectric element as well as noise due to a power source in the manner that the induction noise of exterior high-frequency noise due to an inductance component in an outer lead wire is removed by connecting a second filter to a drain electrode of a FET, and the high-frequency interior noise is removed by installing a first filter between the pyroelectric element and FET. Therefore, a body sensing signal can be obtained by using only one pyroelectric element.
