Query: Rank-Modulation Rewrite Coding for Flash Memories   The current flash memory technology focuses on the cost minimization of its
static storage capacity. However, the resulting approach supports a relatively
small number of program-erase cycles. This technology is effective for consumer
devices (e.g., smartphones and cameras) where the number of program-erase
cycles is small. However, it is not economical for enterprise storage systems
that require a large number of lifetime writes. The proposed approach in this
paper for alleviating this problem consists of the efficient integration of two
key ideas: (i) improving reliability and endurance by representing the
information using relative values via the rank modulation scheme and (ii)
increasing the overall (lifetime) capacity of the flash device via rewriting
codes, namely, performing multiple writes per cell before erasure. This paper
presents a new coding scheme that combines rank modulation with rewriting. The
key benefits of the new scheme include: (i) the ability to store close to 2
bits per cell on each write with minimal impact on the lifetime of the memory,
and (ii) efficient encoding and decoding algorithms that make use of
capacity-achieving write-once-memory (WOM) codes that were proposed recently.
