Interface, memory system, and access control method

摘要

An interface includes a controller that divides a burst access command into a plurality of command cycles and supplies the plurality of command cycles to a storage device including a plurality of blocks, and a block address converter that outputs an address at a first command cycle of the plurality of command cycles. The address is obtained by shifting at least one bit of an external block address input in response to the burst access command. The address is supplied to the storage device at the first command cycle, and the external block address is supplied to the storage device at a command cycle other than the first command cycle.
