Embodiment

[0029] figure 1 is a block diagram showing a memory chip according to an embodiment of the present invention. The memory chip 100 may include a memory 120 and a controller 110 for controlling the memory 120 and processing data transmission between the memory chip 100 and the host 50 . According to an embodiment of the present invention, the controller 110 and the memory 120 may be a controller die and a memory die respectively, and are packaged together in the memory chip 100 . The memory chip 100 can be coupled to a host 50 through an interface 60 . It is worth noting that, for simplicity of illustration, figure 1 It is shown as a simplified block diagram in which only the parts relevant to the present invention are shown. However, those skilled in the art should understand that the touch device may also include other circuit elements not shown in the figure, so the present invention is not limited to the content shown in the figure. The memory chip 100 and the host 50 ca...

Abstract

A memory chip and data protection method.The memory chip, coupled with a host, including memory and controller.The memory is used to load multiple start -up image documents with the same content.The controller is coupled to the memory to process the data transmission between the memory chip and the host.The controller further determines whether the memory chip enters the start -up mode for the first time, and when the memory chip enters the startup mode for the first time, the controller access the memory to obtain a correct start -up image document from multiple start -up image documents.And transmit the correct start -up image document to the host.

Description

technical field [0001] The invention relates to a system and method capable of effectively protecting correct data, in particular to a system and method capable of protecting correct data in a memory chip. Background technique [0002] In recent years, more and more types of electronic products have been developed, such as mobile phones, tablet computers, MP3 players, portable hard drives, satellite navigation, digital cameras, handheld game devices and so on. Electronic products are usually equipped with memory devices to store data necessary for the operation of the host computer in the electronic product system, as well as personal data of users. [0003] Since the data necessary for the operation of the host is used to start and initialize the host and cause the electronic device to start normal operation, in order to prevent the electronic product system from being damaged due to the data damage of the memory device, an effective Systems and methods for protecting corr...
