Abstract
A controller controls an operation of a semiconductor memory device including a plurality of memory blocks. The controller includes a command generator, a sudden power off (SPO) sensor, an SPO information storage, and a block scan controller. The command generator generates a command for controlling the semiconductor memory device. The SPO sensor generates an SPO sensing signal by sensing occurrence of SPO. The SPO information storage stores SPO block information indicating a memory block that is a target of a current operation (target memory block) in response to the SPO sensing signal. The block scan controller controls the command generator to perform a scan operation on the plurality of memory blocks, except for the target memory block, in response to the SPO block information.
