Duality between erasures and defects
Yongjune Kim, B. V. K. Vijaya Kumar
We investigate the duality of the binary erasure channel (BEC) and the binary defect channel (BDC). This duality holds for channel capacities, capacity achieving schemes, minimum d…
Locally rewritable codes for resistive memories
Yongjune Kim, Abhishek A. Sharma, Robert Mateescu +4
We propose locally rewritable codes (LWC) for resistive memories inspired by locally repairable codes (LRC) for distributed storage systems. Small values of repair locality of LRC…
Structured Hough Voting for Vision-based Highway Border Detection
Zhiding Yu, Wende Zhang, B. V. K. Vijaya Kumar +1
We propose a vision-based highway border detection algorithm using structured Hough voting. Our approach takes advantage of the geometric relationship between highway road borders…
Writing on dirty flash memory
Yongjune Kim, B. V. K. Vijaya Kumar
The most important challenge in the scaling down of flash memory is its increased inter-cell interference (ICI). If side information about ICI is known to the encoder, the flash me…
Coding scheme for 3D vertical flash memory
Yongjune Kim, Robert Mateescu, Seung-Hwan Song +2
Recently introduced 3D vertical flash memory is expected to be a disruptive technology since it overcomes scaling challenges of conventional 2D planar flash memory by stacking up c…
Maximum Margin Vector Correlation Filter
Vishnu Naresh Boddeti, B. V. K. Vijaya Kumar
Correlation Filters (CFs) are a class of classifiers which are designed for accurate pattern localization. Traditionally CFs have been used with scalar features only, which limits…
On the Duality of Erasures and Defects
Yongjune Kim, B V K Vijaya Kumar
In this paper, the duality of erasures and defects will be investigated by comparing the binary erasure channel (BEC) and the binary defect channel (BDC). The duality holds for cha…
Redundancy Allocation of Partitioned Linear Block Codes
Yongjune Kim, B. V. K. Vijaya Kumar
Most memories suffer from both permanent defects and intermittent random errors. The partitioned linear block codes (PLBC) were proposed by Heegard to efficiently mask stuck-at def…
Coding for Memory with Stuck-at Defects
Yongjune Kim, B. V. K. Vijaya Kumar
In this paper, we propose an encoding scheme for partitioned linear block codes (PLBC) which mask the stuck-at defects in memories. In addition, we derive an upper bound and the es…
Modulation Coding for Flash Memories
Yongjune Kim, Kyoung Lae Cho, Hongrak Son +4
The aggressive scaling down of flash memories has threatened data reliability since the scaling down of cell sizes gives rise to more serious degradation mechanisms such as cell-to…
