Patent application number | Description | Published |
20090095955 | SEMICONDUCTOR INTEGRATED CIRCUIT AND TESTING METHOD THEREOF - A semiconductor integrated circuit including a detector and a secure checker. The detector generates a detection signal upon sensing an abnormal state in an operating environment of the semiconductor integrated circuit. The secure checker generates a check signal to find an operating condition of the detector and receives the detection signal. The detector activates the detection signal in response to the check signal. | 04-16-2009 |
20090113546 | MEMORY SYSTEM FOR SENSING ATTACK - A memory system includes a main memory, a sub-memory, a controller, first and second data readers and a comparator. The main memory stores data and the sub-memory stores data extracted from the data stored in the main memory for detection of an attack. The controller controls operations of the memory system through interfacing with a host. The first data reader is configured to read first data from the main memory based on address information from the controller. The second data reader is configured to store information relating to second data stored in the sub-memory and to read the second data from the sub-memory based on address information from the controller which is the same as the address information received by the first data reader. The comparator compares the first data read by the first data reader with the second data read by the second data reader to detect the attack. | 04-30-2009 |
20110101114 | Memory System and Data Reading Method Thereof - A memory system includes a memory and a memory controller operating to control the memory. The memory includes a random accessible memory including a memory cell array operable in a random access mode, a NAND flash memory, and a selection circuit making the memory controller operate either one of the random accessible memory or the NAND flash memory. | 05-05-2011 |
20110225351 | MEMORY CARD AND MEMORY SYSTEM HAVING THE SAME - A memory card includes: a first memory chip responding to all commands input externally; and a second memory chip responding to commands, among the commands input externally, relevant to reading, programming, and erasing operations with data. Card identification information stored in the first memory chip includes capacity information corresponding to a sum of sizes of the first and second memory chips. The plurality of memory chips of the memory card are useful in designing the memory card with storage capacity in various forms. | 09-15-2011 |
20120300548 | MEMORY SYSTEM AND DATA READING METHOD THEREOF - A memory system includes a memory and a memory controller operating to control the memory. The memory includes a random accessible memory including a memory cell array operable in a random access mode, a NAND flash memory, and a selection circuit making the memory controller operate either one of the random accessible memory or the NAND flash memory. | 11-29-2012 |
20140233794 | METHOD, APPARATUS AND MEDICAL IMAGING SYSTEM FOR TRACKING MOTION OF ORGAN - A method of tracking motion of an organ, includes receiving organ shape data that includes a shape of an organ of an examinee at a moment of motion of the examinee, and loading first to Nth interpolation curves that represent spatiotemporal motion of respective organs of other examinees, the organs of the other examinees being the same type as the organ of the examinee. The method further includes estimating an interpolation curve that represents a spatiotemporal motion of the organ of the examinee based on the first to Nth interpolation curves and the organ shape data. | 08-21-2014 |
20140294299 | IMAGE PROCESSING APPARATUS AND METHOD - An apparatus and method for out-focusing a color image based on a depth image, the method including receiving an input of a depth region of interest (ROI) desired to be in focus for performing out-focusing in the depth image, and applying different blur models to pixels corresponding to the depth ROI, and pixels corresponding to a region, other than the depth ROI, in the color image, thereby performing out-focusing on the depth ROI. | 10-02-2014 |
20140350403 | APPARATUS FOR PROCESSING ULTRASONIC IMAGE AND METHOD THEREOF - An ultrasonic imaging method includes emitting ultrasonic pulses in different directions and acquiring ultrasonic echo signals from an object, calculating an attenuation rate of the ultrasonic echo signals, correcting the acquired ultrasonic echo signals based on the attenuation rate, and outputting the corrected ultrasonic echo signals as an ultrasonic image. | 11-27-2014 |
20150015818 | METHOD OF SWITCHING GUEST-HOST DUAL FREQUENCY LIQUID CRYSTAL BY USING BACK FLOW - Provided are methods of switching guest-host dual frequency liquid crystals by using a back flow. In the case of a shutter having a dual frequency liquid crystal layer between two transparent substrates, such a method includes: applying a first voltage having a first frequency to the dual frequency liquid crystal layer; and applying a second voltage having a second frequency to the dual frequency liquid crystal, the second frequency being higher than the first frequency, wherein the second voltage is higher than a threshold voltage that generates a back flow around liquid crystals of the dual frequency liquid crystal layer, and the first voltage is lower than the threshold voltage. | 01-15-2015 |
