| 20090020805 | NON-VOLATILE MEMORY DEVICES AND METHODS OF FORMING THE SAME - A non-volatile memory device includes a dielectric layer between a charge storage layer and a substrate. Free bonds of the dielectric layer can be reduced to reduce/prevent charges from leaking through the free bonds and/or from being trapped by the free bonds. As a result, data retention properties and/or durability of a non-volatile memory device may be enhanced. | 01-22-2009 |
| 20090027967 | NON-VOLATILE MEMORY DEVICE PROGRAMMING SELECTION TRANSISTOR AND METHOD OF PROGRAMMING THE SAME - A memory system includes a flash memory device and a memory controller for controlling the flash memory device. The flash memory device includes a cell string and a selection transistor connected in series to the cell string. The cell string includes multiple series-connected memory cells. The selection transistor has the same structure as a memory cell of the series-connected memory cells, and is programmed through channel hot electron injection. | 01-29-2009 |
| 20090040836 | NAND flash memory device and method of programming the same - Provided are a NAND flash memory device and a method of programming the same. The NAND flash memory device may include a cell array including a plurality of pages; a page buffer storing program data of the pages; a data storage circuit providing program verification data to the page buffer; and a control unit. The control unit may program the pages and verify the pages using the program verification data following the programming of at least two of the pages. | 02-12-2009 |
| 20090097546 | SYSTEM AND METHOD FOR ENHANCED VIDEO COMMUNICATION USING REAL-TIME SCENE-CHANGE DETECTION FOR CONTROL OF MOVING-PICTURE ENCODING DATA RATE - Disclosed is a method for detecting a scene change in real time in order to control a moving-picture encoding data rate, the method including: dividing a current frame into a plurality of regions, and calculating a dissimilarity metric (DM) of each divided region; determining if the dissimilarity metric of each divided region is beyond a preset reference value; calculating the number of regions, the dissimilarity metric of which is beyond the preset value, in the current frame; and determining that a scene change occurs in the current frame, when the number of regions, the dissimilarity metric of which is beyond the reference preset value, is equal to or greater than a preset threshold value. | 04-16-2009 |
| 20090230451 | Semiconductor device capable of suppressing short channel effect and method of fabricating the same - A semiconductor device includes a semiconductor substrate including at least one memory channel region and at least one memory source/drain region, the memory channel region and the memory source/drain region being arranged alternately, and at least one word line on the memory channel region, wherein the memory source/drain region has a higher net impurity concentration than the memory channel region. | 09-17-2009 |
| 20100027617 | METHOD AND APPARATUS FOR COMPRESSING A REFERENCE FRAME IN ENCODING/DECODING MOVING IMAGES - Provided is a method of compressing a reference frame in encoding or decoding moving images. A reference frame to be compressed is divided into basic processing blocks. The basic processing blocks are divided into sub-blocks. A maximum value and a minimum value of pixels within each sub-block are calculated. A necessary bit length needed for compression of each sub-block is obtained based on a difference between the maximum value and the minimum value. An average bit length of the sub-blocks within the basic processing block is calculated based on the calculated necessary bit lengths of the sub-blocks. Bits are variably allocated to each sub-block by adjusting the necessary bit length of each sub-block so that the average bit length of the sub-blocks within a corresponding basic processing block is less than or equal to a preset required bit length. Each sub-block is compressed to the allocated bits. | 02-04-2010 |
| 20100046625 | APPARATUS AND METHOD FOR VIDEO ENCODING AND DECODING - A method and apparatus for encoding an image based on a video sensor structure are provided. The method includes acquiring an image to be encoded; separating the acquired image into respective color components; creating a predicted image for each of the color components, and creating a residual image between the predicted image and the acquired image; and performing transform encoding on each of the color components individually by applying the residual image to a transformation formula. | 02-25-2010 |
| 20100317157 | CELL ARRAY OF SEMICONDUCTOR MEMORY DEVICE AND A METHOD OF FORMING THE SAME - A cell array includes a semiconductor substrate including an active region comprising a first region, a second region, and a transition region, the second region being separated from the first region by the transition region, wherein a top surface of the second region is at a different level than a top surface of the first region. The cell array also includes a plurality of word lines crossing over the first region. The cell array also includes a selection line crossing over the active region, wherein at least a portion of the selection line is located over the transition region. | 12-16-2010 |
