Yu Cai, Gulay Yalcin, Onur Mutlu, Erich F. Haratsch, Osman Unsal, Adrian Cristal, Ken Mai
2014 The 2014 ACM international conference on Measurement and modeling of computer systems - SIGMETRICS '14  
Based on our analyses, we propose a new method for correcting errors in a flash memory page, neighborcell assisted correction (NAC).  ...  a neighbor cell value and use the re-read values to correct the cells that have neighbors with that value.  ...  ACKNOWLEDGMENTS We thank the anonymous reviewers for helpful feedback.  ...

Architectural Techniques for Improving NAND Flash Memory Reliability [article]

Yixin Luo
2018 arXiv   pre-print
We aim to improve flash reliability with a multitude of low-cost architectural techniques.  ...  Raw bit errors are common in NAND flash memory and will increase in the future. These errors reduce flash reliability and limit the lifetime of a flash memory device.  ...  Early MLC flash memories used oneshot programming, where both the LSB and MSB pages of a wordline are programmed at the same time.  ...

Flash-Based Security Primitives: Evolution, Challenges and Future Directions

Holden Gordon, Jack Edmonds, Soroor Ghandali, Wei Yan, Nima Karimian, Fatemeh Tehranipoor
2021 Cryptography  
Flash memory has been given a spotlight in recent years, with the question of whether or not it can prove useful in a security role.  ...  Because of inherent process variation in the characteristics of flash memory modules, they can provide a unique fingerprint for a device and have thus been proposed as locations for hardware security primitives  ...  In an effort to reduce the cell-to-cell programming interference in flash memory, designers employ a unique two-step programming sequence that separates the programming of the LSB and MSB of MLC flash  ...

Design, Validation and Correlation of Characterized SODIMM Modules Supporting DDR3 Memory Interface

Vemula Harini
2013 IOSR Journal of Electronics and Communication Engineering  
In any computing environment, it is necessary for the processor to have fast accessible RAM that allows temporary storage of data.  ...  DDR3-SODIMM module is a key component in the memory interface and is becoming increasingly important in enabling higher speeds.  ...  On the other hand, multi-level per cell (MLC) technology enabling a memory cell to store more than 1 bit has been developed to increase the storage density of NAND flash memory.  ...

Flash-aware Database Management Systems

Sergej Hardock
2020
In other words, FTL creates a black-box over Flash memory and emulates the behavior of HDDs.  ...  FTL is a set of Flash management tasks that typically run on device and mask the native behavior of Flash memory.  ...  Thus, for instance, some manufactures produce MLC Flash chips with four Flash pages per wordline: two LSB pages (LSB-odd, LSB-even) and two MSB pages (MSB-odd, MSB-even).  ...

Writing on Dirty Memory

Yongjune Kim
2018
The idea of coding techniques for memory with stuck-at defects is employed to handle critical problems of flash memories and resistive memories.  ...  For 2D planar flash memories, we propose a coding scheme that combats the ICI, which is a primary challenge of 2D planar flash memories.  ...  In 2 bits per cell flash memories, the least significant bit (LSB) and most significant bit (MSB) are mapped to two separate pages: LSB page and MSB page.  ...
