Inside Solid State Drives (SSDs)

The revised second edition of this respected text provides a state-of-the-art overview of the main topics relating to solid state drives (SSDs), covering NAND flash memories, memory controllers (including booth hardware and software), I/O interfaces (PCIe/SAS/SATA), reliability, error correction codes (BCH and LDPC), encryption, flash signal processing and hybrid storage.Updated throughout to include all recent work in the field, significant changes for the new edition include:A new chapter on flash memory errors and data recovery procedures in SSDs for reliability and lifetime improvementUpdated coverage of SSD Architecture and PCI Express Interfaces moving from PCIe Gen3 to PCIe Gen4 and including a section on NVMe over fabric (NVMf)An additional section on 3D flash memoriesAn update on standard reliability procedures for SSDsExpanded coverage of BCH for SSDs, with a specific section on detectionA new section on non-binary Low-Density Parity-Check (LDPC) codes, the most recent advancement in the fieldA description of randomization in the protection of SSD data against attacks, particularly relevant to 3D architecturesThe SSD market is booming, with many industries placing a huge effort in this space, spending billions of dollars in R&D and product development. Moreover, flash manufacturers are now moving to 3D architectures, thus enabling an even higher level of storage capacity. This book takes the reader through the fundamentals and brings them up to speed with the most recent developments in the field, and is suitable for advanced students, researchers and engineers alike.
