Memory system and operating method for programming data in super blocks
A memory system includes a memory device including a plurality of memory chips each including a plurality of memory blocks grouped as one or more super blocks, wherein the memory blocks each include a plurality of pages suitable for storing write data requested from a host, and a controller suitable for checking a size of the write data and free pages of the super blocks, determining a first super block corresponding to the checked size of the write data based on the checked free pages among the super blocks, and programming the write data in memory blocks of the first super block.

wherein the controller programs dummy data or null data in a remaining page region of the programmable page, after programming the write data.
7. The memory system according to claim 1 , wherein, when two or more super blocks are checked as the first super block among the super blocks, the controller determines one of the two or more super blocks as the first super block based on a priority of a page address.
8. The memory system according to claim 1 , wherein, when two or more super blocks are checked as the first super block among the super blocks, the controller determines one of the two or more super blocks as the first super block based on program performance.
9. A method for operating a memory system, comprising:
checking a size of write data corresponding to a write command received from a host, and
checking free pages of a plurality of super blocks, wherein a plurality of memory blocks of a memory device are grouped as the super blocks and each include a plurality of pages;
determining a first super block corresponding to the checked size of the write data based on the checked free pages among the super blocks; and
programming the write data in memory blocks of the first super block,
wherein, the respective super blocks have a same size,
