Memory chips and data protection methods

摘要

A memory chip coupled to a host includes a memory and a controller. Multiple boot images having the same content are pre-loaded in the memory. The controller is coupled to the memory for processing data transmission between the memory chip and the host. The controller further determines whether the memory chip enters a boot mode for the first time. When the memory chip enters the boot mode for the first time, the controller accesses the memory so as to obtain a correct boot image from the boot images and transmits the correct boot image to the host.

1. A memory chip, coupled to a host, comprising:
a memory, pre-loading a plurality of boot images, wherein the boot images have the same content; and a controller, coupled to the memory, processing data transmissions between the memory chip and the host, wherein the controller further determines whether the memory chip enters a boot mode for the first time according to a first flag, and when the memory chip enters the boot mode for the first time, the controller accesses the memory to obtain a correct boot image from the boot images and transmits the correct boot image to the host.
