Operation methods, memory systems, system and readable storage media

An operation method of a memory system, comprising:

• receiving an executable file in a set format via a communication interface of the memory system, wherein the executable file comprises:
• a file header;
• and
• a plurality of pieces of executable code, wherein one of the plurality of pieces of executable code comprises:
• first code segment data;
• and
• a code segment header configured to indicate a first memory location of the first code segment data in the memory system;
• and
• running a first handler, wherein the first handler performs the following when running:
• parsing the executable file to obtain a plurality of pieces of code segment data and the code segment header corresponding to each of the plurality of pieces of code segment data contained in the executable file, the plurality of pieces of code segment data including the first code segment data and second code segment data;
• and
• writing a corresponding piece of code segment data into a corresponding memory location according to each code segment header, wherein the first code segment data is transmitted to the first memory location to cause download of a first upgrade for the memory system, the first upgrade to correspond to the first memory location and a second upgrade from the second code segment data to correspond to a second memory location, the first memory location different than the second memory location.

• and
• a host coupled to the memory system and configured to control the memory system.
