    摘要: According to one embodiment, a controller searches a threshold voltage distribution of first memory cells corresponding to a first processing unit that is one processing unit among a plurality of processing units, and acquires a first read voltage. The controller calculates a second read voltage that is a read voltage for second memory cells corresponding to a second processing unit based on the acquired first read voltage and a first relation. The controller ads data from third memory cells included in the second memory cells by using the calculated second read voltage.
