A memory system includes a memory and a controller. The memory is configured to store a number of valid data in each of a plurality of logical blocks and a number of valid data for each of a plurality of banks in each of the logical blocks. The controller is configured to: select logical blocks of garbage collection target candidates based on the numbers of valid data in the logical blocks; calculate a maximum value among the numbers of valid data for the banks in each of the logical blocks of the garbage collection target candidates as a respective comparison value; and select one of the logical blocks of the garbage collection targets based on comparing the respective comparison values of the logical blocks of the garbage collection target candidates with each other.
