In order to meet the demands of data-hungry applications, modern data storage systems are expected to be increasingly denser. This is a challenging endeavor, and storage engineers are continuously trying to provide novel technologies. However, these new technologies are typically associated with an increase in the number and types of errors, making the goal of securing highly-reliable dense storage devices a tricky challenge. This dissertation focuses on analyzing the errors in addition to providing novel and efficient error correcting coding schemes that are capable of overcoming the aforementioned challenge. In particular, through informed exploitation of the underlying channel characteristics of the storage device being studied, we provide frameworks for systematically generating error correcting codes with mathematical guarantees that offer performance improvements in orders of magnitude relative to the prior state-of-the-art. First, we present a technique to predict the performance of codes given the existence of certain error-prone structures in the graph representation of these codes. Next, we introduce a general framework for the code optimization of non-binary graph-based codes, which works for various interesting channels. Finally, we derive an approach to design high performance spatially-coupled codes particularly for magnetic recording applications. Our frameworks are based on mathematical tools drawn from coding theory and information theory, and rely on advanced mathematical techniques from probability theory, linear algebra, graph theory, combinatorics, and optimization. The proposed frameworks have a vast variety of applications that include both magnetic recording and Flash memory systems. Our frameworks lead to a practical, effective tool for storage engineers to use multi-dimensional storage devices with confidence.

Download and read online ebook Advanced Error Control Techniques for Data Storage Systems write by Erozan M. Kurtas. This book was released on 2018-10-03. Advanced Error Control Techniques for Data Storage Systems available in PDF, EPUB and Kindle. With the massive amount of data produced and stored each year, reliable storage and retrieval of information is more crucial than ever. Robust coding and decoding techniques are critical for correcting errors and maintaining data integrity. Comprising chapters thoughtfully selected from the highly popular Coding and Signal Processing for Magnetic Recording Systems, Advanced Error Control Techniques for Data Storage Systems is a finely focused reference to the state-of-the-art error control and modulation techniques used in storage devices. The book begins with an introduction to error control codes, explaining the theory and basic concepts underlying the codes. Building on these concepts, the discussion turns to modulation codes, paying special attention to run-length limited sequences, followed by maximum transition run (MTR) and spectrum shaping codes. It examines the relationship between constrained codes and error control and correction systems from both code-design and architectural perspectives as well as techniques based on convolution codes. With a focus on increasing data density, the book also explores multi-track systems, soft decision decoding, and iteratively decodable codes such as Low-Density Parity-Check (LDPC) Codes, Turbo codes, and Turbo Product Codes. Advanced Error Control Techniques for Data Storage Systems offers a comprehensive collection of theory and techniques that is ideal for specialists working in the field of data storage systems.

Error Correction Codes for Non-Volatile Memories available in PDF, EPUB and Kindle. Nowadays it is hard to find an electronic device which does not use codes: for example, we listen to music via heavily encoded audio CD's and we watch movies via encoded DVD's. There is at least one area where the use of encoding/decoding is not so developed, yet: Flash non-volatile memories. Flash memory high-density, low power, cost effectiveness, and scalable design make it an ideal choice to fuel the explosion of multimedia products, like USB keys, MP3 players, digital cameras and solid-state disk. In ECC for Non-Volatile Memories the authors expose the basics of coding theory needed to understand the application to memories, as well as the relevant design topics, with reference to both NOR and NAND Flash architectures. A collection of software routines is also included for better understanding. The authors form a research group (now at Qimonda) which is the typical example of a fruitful collaboration between mathematicians and engineers.
