20120011596 | SYSTEM AND METHOD OF PROTECTING DIGITAL MEDIA CONTENTS - A system and method of protecting digital media contents, which maintain compatibility with an existing system and block any attempt to illegally use the digital media contents having various formats, and which reduce a system load and maximize a possibility of reusing the digital media contents. The system includes a packager for analyzing a format of contents and encoding at least a portion of a data region located in a payload of the contents, and for generating encoded contents by inserting encoding information including at least one of an encoding key value and contents information into the contents; and a digital rights management (DRM) server for receiving a request for a license and the encoding information from an external device which receives the encoded contents, for confirming the encoding information and then generating a license which is used to decode the encoded contents, and for providing the generated license to the external device. | 01-12-2012 |
20140025887 | NONVOLATILE MEMORY DEVICE AND RELATED DATA MANAGEMENT METHOD - A method of operating a nonvolatile memory device comprising a plurality of memory blocks comprises storing first data and second data to be stored in a hot memory block of the memory blocks in a first buffer, transferring the first data stored in the first buffer to a second buffer to program the first data in the hot memory block, and generating RAID parity data based on the first and second data, wherein the RAID parity data and the first data form part of the same write stripe. | 01-23-2014 |
20140119124 | SEMICONDUCTOR MEMORY SYSTEMS USING REGRESSION ANALYSIS AND READ METHODS THEREOF - A memory system includes: a bit counter and a regression analyzer. The bit counter is configured to generate a plurality of count values based on data read from selected memory cells using a plurality of different read voltages, each of the plurality of count values being indicative of a number of memory cells of a memory device having threshold voltages between pairs of the plurality of different read voltages. The regression analyzer is configured to determine read voltage for the selected memory cells based on the plurality of count values using regression analysis. | 05-01-2014 |
