Flash memory is a crucial data-storage technology in today’s and tomorrow’s information ecosystem. Various channel-coding approaches have been proposed for increasing the efficiency of flash memories. I will discuss one of these approaches, called “write-once memory” (WOM) coding, in which the memory is rewritten before it is being erased. WOM coding has the potential to significantly increase the lifetime of flash memories, which would allow for greater storage densities. While the area have seen major progress in recent years, current solutions are still not adequate for practical use. I will present recent work that aim to address this gap, using modern techniques of entropy polarization and message passing on sparse-graph codes.
