Publication: Writing without Disturb on Phase Change Memories by Integrating Coding and Layout Design

MEMSYS '15 Proceedings

We integrate coding techniques and layout design to eliminate write-disturb in phase change memories (PCMs), while enhancing lifetime and host-visible capacity. We first propose a checkerboard configuration for cell layout to eliminate write-disturb while doubling the memory lifetime. We then introduce two methods to jointly design Write-Once-Memory (WOM) codes and layout.
