Computer system and operating method thereof, memory system, controller and storage

A method of operating a computer system, wherein the computer system comprises:

• a host;
• a controller;
• and
• a memory, wherein memory space of the memory is divided into at least two types of data partitions, the at least two types comprising:
• a first type corresponding to external data of an electronic device comprising the computer system;
• and a second type corresponding to internal data of the electronic device,
• wherein the method comprises:
• sending, by the host, a write command to the controller, wherein the write command comprises first data to be written into the memory and a logical unit number to which the first data is to be written, and the logical unit number is specified according to the type of the data partition;
• and
• instructing, by the controller, the memory to write the first data into a physical memory block corresponding to the logical unit number in the memory according to the logical unit number,
• wherein a physical memory block corresponding to the first type of data partition is different from a physical memory block corresponding to the second type of data partition.

A memory system, comprising:

• a memory, wherein memory space of the memory is divided into at least two types of data partitions, the at least two types comprising:
• a first type corresponding to external data of an electronic device comprising a computer system;
• and a second type corresponding to internal data of the electronic device, and wherein the computer system comprises the memory system;
• and
• a controller configured to:
• receive a write command, wherein the write command comprises first data to be written into the memory and a logical unit number to which the first data is to be written, and the logical unit number is specified according to the type of the data partition;
• and
• instruct the memory to write the first data into a physical memory block corresponding to the logical unit number in the memory according to the logical unit number,
• wherein a physical memory block corresponding to the first type of data partition is different from a physical memory block corresponding to the second type of data partition.
