20140120379 | BATTERY PACK - A battery pack includes a bare cell; a holder case positioned at the top of the bare cell; and a top case that covers the holder case. In the battery pack, a protruding portion is formed in a short side portion of the holder case, and a receiving portion is formed at a position corresponding to the protruding portion in the top case. Accordingly, the protruding portion is inserted into the receiving portion, so that it is possible to provide the battery pack stronger against external impact. | 05-01-2014 |

20140241076 | SEMICONDUCTOR MEMORY DEVICE, METHOD OF TESTING THE SAME AND METHOD OF OPERATING THE SAME - A method of testing a semiconductor memory device is provided. Data is written to a plurality of memory cells disposed in a memory cell block of the semiconductor memory device. A first driving voltage is applied to a first group of word lines. A second driving voltage is applied to a second group of word lines. Each word line of the first group of the word lines is interposed between two neighboring word lines of the second group of the word lines. The first driving voltage has a voltage level different from that of the second driving voltage. The data is read from first memory cells coupled to the first group to determine whether each of the first memory cells is defective. | 08-28-2014 |
