A method of extracting an important keyword by an important keyword extracting server, the method includes receiving a set of one or more documents from a network, receiving one or more user defined keywords from a user terminal, calculating, by the server, a relative importance value for each of words detected in the set of documents, determining, by the server, a weight for each of the words based on the one or more user defined keywords, applying, by the server, the weight for each of the words to the relative importance value for each of the words, determining, by the server, at least one of the words to be the important keyword based on the relative importance value to which the weight is applied and transmitting, by the server, the important keyword to the user terminal. Therefore, the method may effectively detect a user defined keyword from at least one document.

A data output circuit and accompanying method for use in a semiconductor memory is disclosed for converting parallel data into serial data and, in particular, for converting the parallel data used in a Double Data Rate Synchronous DRAM (DDR) into serial data. The data output circuit and accompanying method intermediately store a falling data synchronized with a rising edge of one clock for a predetermined time period up to a next rising edge. Final data is merged in response to the stored falling data, thereby preventing failure between the data and ensuring a wide frequency range. Accordingly, the data output circuit and the method may be applied to all kinds of DDR products to prevent data failures therein.

Apparatus and a method for a data output circuit in a semiconductor memory

The present invention relates to a sensing current reduction device for a semiconductor memory device, and a method therefor, which can considerably reduce a sensing current occupying a great part of an operating current and consume less power, by controlling a bit line sense amplifier to be operated after receiving a column address, and control a long-time operation not to be carried out after applying the row address. Accordingly, a time from latching a row address signal to receiving a column address signal is sharply decreased. As a result, an access time is reduced, thus achieving the high speed operation.

Sensing current reduction device for semiconductor memory device and method therefor

A predecoder of a semiconductor memory device which is capable of selectively inverting a signal output from a decoding unit adapted to decode internal addresses generated from address buffers, thereby achieving an improvement in the utility thereof. The predecoder includes a selection unit for selectively outputting one of the signals having different logic levels while being generated based on an output signal from the decoding unit. Where the predecoder is applied to a cell repair circuit using antifuses, it is possible to reduce the layout area of the cell repair circuit, thereby achieving a reduction in the chip size. This results in a reduction in the costs of the chip.

An antifuse stabilizing apparatus for a memory device stabilizes a programming process of an antifuse. A serial antifuse block has a plurality of antifuses being interconnected in series, and is programmed by applying a voltage being higher than an appropriate applying voltage of each antifuse. An antifuse programming block applies a program voltage being higher than the appropriate applying voltage to both ends of each antifuse in order to program the antifuses. A high voltage portion and a low voltage portion check a coupling state of the antifuses of the serial antifuse block. The applying voltage higher than the appropriate applying voltage is a voltage to be applied to both ends of each antifuse by the antifuse programming block. As a result, all circuits of using an antifuse whose appropriate applying voltage is lower than a power-supply voltage of the peripheral circuit can use the antifuse stably without using an additional circuit.
