Advanced algebraic and graph-based ECC schemes for modern NVMs

Abstract

In this chapter, we discuss advanced error-correcting code techniques. In particular, we focus on two complementary strategies, asymmetric algebraic codes and non-binary low-density parity-check (LDPC) codes. Both of these techniques are inspired by traditional coding theory; however, in both cases, we depart from classical approaches and develop new concepts specifically designed to take advantage of inherent channel characteristics that describe non-volatile memories.
