Numerically controlled system and numerically controlled machine tool

An NCS, comprising a storage and a MCU capable of reading data from and writing data into the storage, wherein the MCU comprises a data buffer, the storage comprises an internal memory and a flash memory, the internal memory is configured to store data and programs which are needed when the MCU is in operation;

• wherein the flash memory comprises at least one of a SD card memory and an eMMC memory, and a fixed built-in NAND-Flash memory;
• the NAND-Flash memory is configured to store system files of the NCS, the SD card memory and the eMMC memory both are configured to store the system files and user data of the NCS;
• when the flash memory uses a combination of the NAND-Flash memory and the SD card memory, the MCU reads the system files stored in the NAND-Flash memory and the user data stored in the SD card memory, the system files stored in the SD card memory are for backup purposes;
• when the flash memory uses a combination of the NAND-Flash memory and the eMMC memory, the MCU reads the system files stored in the NAND-Flash memory and the user data stored in the eMMC memory, the system files stored in the eMMC memory are for backup purposes;
• when the flash memory uses a combination of the NAND-Flash memory, the SD card memory and the eMMC memory, the MCU reads the system files stored in one of the NAND-Flash memory and the SD card memory, the system files stored in the other one of the NAND-Flash memory and the SD card memory are for backup purposes;
• and reads the user data stored in one of the SD card memory and the eMMC memory, the user data stored in the other one of the SD card memory and the eMMC memory is for backup purposes.
