INTEGRATED CHIP AND DATA PROCESSING METHOD

An integrated chip and a data processing method are provided, to improve system security and service processing efficiency of a system. The integrated chip includes: an application processor, configured to write first data into an off-chip memory in a normal secure mode by using a storage controller, where an address of the first data in the off-chip memory is a first address; a security processor, configured to send a first read instruction to the storage controller in an enhanced secure mode, where the first read instruction is used to request to read the first data at the first address; and the storage controller, configured to control the security processor to read the first data from the off-chip memory.
