A write error preventing circuit for a semiconductor memory device prevents an erroneous reading operation an input buffer compares an externally applied write enable signal to an effective level signal, which is preset therein. A write error preventive circuit outputs a disable signal to the input buffer during an interval of time when a ground voltage bounces in accordance with an internal output signal from a NAND gate of an output buffer. The circuit prevents the outputting of a write signal from the input buffer during a read operation in accordance with the internal output signal from the output buffer when the ground voltage bounces.

Isolated and/or recombinant nucleic acids encoding mycobacterial methionyl-tRNA synthetase have been characterized. Recombinant DNA constructs and vectors having a sequence which encodes mycobacterial methionyl-tRNA synthetase have been made, and can be used for the construction of tester strains as well as for the production of isolated and/or recombinant methionyl-tRNA synthetases. These enzymes or portions thereof are useful in the biochemical separation of methionine and quantification of methionine or ATP, and for producing antibodies useful in the purification and study of the enzyme, for example. Host cells and methods useful for producing recombinant mycobacterial methionyl-tRNA synthetases are described, as are tester strains, which are cells engineered to rely on the function of the tRNA synthetase encoded by an introduced cloned gene. Tester strains can be used to identify inhibitors of the essential tRNA synthetase enzyme encoded by the introduced cloned gene, and thus provide a means to assess the antimicrobial effect and specificity of the inhibitor without employing slow-growing, pathogenic strains of mycobacteria, such as Mycobacterium tuberculosis.

A column repair circuit for a semiconductor memory having an input/output selection circuit for inputting a control signal, selecting a bit line and a bit bar line corresponding to a faulty memory cell and replacing the selected bit line and bit bar line with a spare bit line and a spare bit bar line. The input/output selection circuit includes an input stage for inputting the control signal, a spare bit line and a spare bit bar line, and a plurality of fuses each having one side connected to the input stage and other side connected to a plurality of resistors. The other side of the resistors are connected to ground for outputting the output signals. The input/output selection circuit further has a plurality of n-channel MOSFETs each including a gate connected to each of the other stages of the plurality of fuses via the resistors in a 2 to 1 manner for inputting the output signals. The drains of the MOSFETS are connected to the spare bit line and spare bit bar line and their sources are connected to each of the plurality of data bit lines and the plurality of data bit bar lines for functioning as a switch. Therefore, the present invention can provide the column repair circuit for a semiconductor memory which is capable of increasing its repair yield by adding the input/output selecting circuit enabling input/output selecting.

A speech recognition system and method based on word-level candidate generation are provided. The speech recognition system may include a speech recognition result verifying unit to verify a word sequence and a candidate word for at least one word included in the word sequence when the word sequence and the candidate word are provided as a result of speech recognition. A word sequence displaying unit may display the word sequence in which the at least one word is visually distinguishable from other words of the word sequence. The word sequence displaying unit may display the word sequence by replacing the at least one word with the candidate word when the at least one word is selected by a user.

A voice/speech recognition client system, a voice recognition server system, and a voice recognition method. The voice recognition system indicates a result of voice recognition in a voice signal inputted from a starting time for voice recognition to an ending time. The voice recognition client comprises: a communication unit that transmits a unit voice signal input at intervals from the starting time to the ending time, to the voice recognition server system at the intervals and receives an intermediate result of voice recognition from the voice recognition server system; and a display unit that displays the intermediate result received between the starting time and the ending time.

A power control system for an LCD monitor having an LCD panel includes a light source unit providing light to the LCD panel, a power supply unit generating a standard low DC current, and a high-voltage generator for converting the lower DC voltage to a relatively high voltage and supplying the high voltage to the light source. The power control system further includes a feedback control unit coupled to the power supply unit for interrupting the operation of the power supply unit when the converted high voltage is determined to be abnormal. The feedback control unit includes a cable, through which a voltage can be induced due to high voltage generated by the high-voltage generator, and a power supply control circuit capable of interrupting the operation of the power supply unit when the converted high voltage is determined to be abnormal by analyzing the induced current.
