Abstract

A portable electronic device with user data access method. The disclosed portable electronic device includes a first non-volatile memory, a central processing unit, an interface and a connector. The first non-volatile memory is configured to store first data. The central processing unit is powered with an operating voltage and is configured to run an operating system. The interface controller is electrically coupled to the first non-volatile memory. The connector is electrically coupled to the interface controller and configured to connect with a host device. When the central processing unit crashes or is not powered with the operating voltage, the interface controller is configured to read the first data stored in the first non-volatile memory and transmit the first data to the host device via the connector.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to user data access technology. Background technique [0002] In portable electronic devices (such as smartphones, tablet computers, etc.), the non-volatile memory used to store user data (such as videos, pictures, files, etc.) is generally connected to the central processing unit of the portable electronic device, and only The central processing unit is allowed to access. If the portable electronic device is abnormal, the central processing unit will not be able to operate, so that the user data in the non-volatile memory cannot be accessed. Contents of the invention [0003] A portable electronic device and a method for accessing user data used therein. [0004] A portable electronic device implemented according to an embodiment of the present application includes a first non-volatile memory, a central processing unit, an interface controller and a connector. The first non-vola...
