1. A method of performing a write operation in a memory system, comprising:
compressing data of a first size unit to generate compressed data; generating a plurality of types of Error Checking and Correction (ECC) information based on the compressed data; combining the compressed data and the plurality of types of ECC information to generate combined information in units of a second size; and writing the combined information in units of the second size into a memory device, wherein the generating of the plurality of types of the ECC information comprises: dividing the compressed data into a plurality of pieces; generating a first type of the ECC information based on a first piece of the compressed data; and generating a second type of the ECC information based on the first piece of the compressed data, the first type of the ECC information, and a second piece of the compressed data.
