Abstract:
A method of reading data in a non-volatile memory device. The method includes reading a plurality of memory cells of a first page in a memory cell array using a first read level, reading a plurality of memory cells of a second page adjacent to the memory cells of the first page using a second read level, determining whether a state of each memory cell of the first page has been changed based on the first read level to verify a threshold voltage of each memory cell of the second page based on the second read level, and revising the state of each memory cell of the second page according to a result of the determination.
Abstract:
A data storage device receives write data and includes a controller configured to determine a characteristic of the write data and provide a first control signal in response to the determined characteristic, a randomizer configured to selectively randomize or not randomize the write data in response to the first control signal to thereby generate randomized write data, and a data storage unit configured to store the randomized write data.
Abstract:
A method setting a read voltage to minimize data read errors in a semiconductor memory device including multi-bit memory cells. In the method, a read voltage associated with a minimal number of read data error is set based on a statistic value of a voltage distribution corresponding to each one of a plurality of voltage states.
Abstract:
The present invention has been made in an effort to provide an apparatus for removing noise for sound/voice recognition removing a TV sound corresponding to a noise signal by using an adaptive filter capable of adapting a filter coefficient in order to remove an analogue signal and performing sound and/or voice recognition and a method thereof.
Abstract:
Disclosed are a memory device and a data decision method. The memory device may include a memory cell array, and a decision unit configured to read first data from the memory cell array via a first channel, perform at least one of a hard and soft decision on the first data using a first number of decision levels set based on characteristics of the first channel, read second data from the memory cell array via a second channel, and perform a soft decision on the second data using a second number of decision levels set based on characteristics of the second channel.
Abstract:
An optical measuring apparatus for measuring optical characteristics of a stereoscopic display device includes a test image supplier for generating a 3D test signal, a 3D display for displaying left-eye image and/or right-eye image based on the 3D test signal supplied from the test image supplier, a image selection member for selectively transmitting the left-eye image and right-eye image to be displayed on the 3D display, and a light measuring device for measuring intensity or color information of the image transmitted via the image selection member.
