Operating method forcing the second operation to fail using a scatter-gather buffer and memory system thereof

Abstract

A memory system includes: a memory device including a memory block, a page buffer, and first and second memory dies; a write buffer suitable for temporarily storing first and second data; a program managing unit suitable for controlling the memory device to sequentially perform first and second program operations on the memory block with the first and second data; a buffer managing unit suitable for managing the write buffer based on a scatter-gather scheme; a failure processing unit suitable for forcing the second program operation to fail, when the first program operation is a failure; and an error handling unit suitable for controlling the program managing unit to perform the first and second program operations again for the first and second data that are temporarily stored in the write buffer when the second program operation is forced to fail.
