Classification: CPC G | IPC G

Claim 0:
1. A controller that controls a semiconductor memory device including a plurality of memory blocks, the controller comprising:
a block manager configured to manage information on the plurality of memory blocks;
a map data manager configured to manage map data for data stored in the plurality of memory blocks; and
a command generator configured to generate a program command for controlling a program operation of the semiconductor memory device,
wherein the command generator generates the program command for the program operation of storing data in a first memory block among the plurality of memory blocks,
wherein the command generator is further configured to determine a second memory block to store dummy data based on the information from the block manager when the first memory block is full by the program operation, and
wherein the second memory block becomes a full state, as the dummy data is stored in the second memory block.
