A memory system comprising:

a nonvolatile memory device including a plurality of memory blocks;
and
a controller suitable for dividing the plurality of memory blocks into a first group and a second group, and controlling the memory blocks included the first group and the second group, respectively,
wherein the controller is further suitable for:
managing all operations except for an erase operation to the memory blocks of the first group through a first operation task;
managing all operations except for an erase operation to the memory blocks of the second group through a second operation task;
and
managing the erase operation to the memory blocks of the first group and the memory blocks of the second group through an erase operation task.

An operating method for a memory system including a nonvolatile memory device having a plurality of memory blocks, the method comprising:

a first step of controlling memory blocks included in a first group among the plurality of memory blocks;
and
a second step of controlling memory blocks included in a second group among the plurality of memory blocks,
wherein the first step includes managing all operations except for an erase operation to the memory blocks of the first group through a first operation task, and managing the erase operation to the memory blocks of the first group through an erase operation task,
wherein the second step includes managing all operations except for an erase operation to the memory blocks of the second group through a second operation task, and managing the erase operation to the memory blocks of the second group through the erase operation task.
