Abstract
A controller of a memory system includes circuitry that generates a first compression unit that is calculated based on first namespace setting information indicating setting of a write-destination namespace, and corresponds to the write-destination namespace. The first compression unit has a size satisfying a constraint that an encryption key for encrypting data to be written into the write-destination namespace is not switched in the first compression unit.
