Abstract
Official abstract text for this publication.
According to one embodiment, a controller executes first refreshing in a case where a first value of a first block is larger than a first threshold and less than a second threshold. The first refreshing includes reprogramming a plurality of second memory cells among a plurality of first memory cells included in the first block.
First claim
Opening claim text (preview).
What is claimed is: 1. A memory system comprising: a nonvolatile memory including a plurality of blocks, the block including a plurality of memory cells; and a controller configured to: in a case where a first value of a first block is larger than a first threshold and less than a second threshold, execute first refreshing, the first refreshing including reprogramming a plurality of second memory cells among a plurality of first memory cells included in the first block, the se…
