Memory chips and data protection methods

A data protection method, comprising:

• pre-loading a plurality of boot images in a memory chip, wherein the boot images have the same content;
• determining whether the memory chip enters a boot mode for the first time according to a first flag, wherein the first flag indicates whether the memory chip stores a plurality of boot images with the same content;
• obtaining a correct boot image from the boot images when the memory chip enters the boot mode for the first time;
• and
• transmitting the correct boot image to a host coupled to the memory chip,
• wherein each boot image comprises a plurality of data blocks, and the step of obtaining the correct boot image from the boot images further comprises:
• determining whether the data blocks of one or more of the boot images are correct;
• and
• loading a plurality of correct data blocks from one or more of the boot images to obtain the correct boot image.
