Embodiments of the present disclosure disclose a flash memory access method and apparatus, and relate to the field of chips, so as to alleviate a problem in the conventional technology that a conflict occurs when a plurality of software subsystems running on one chip access a flash memory. An example solution is: The method is applied to a system on chip including an access controller and a plurality of processor cores, where the plurality of processor cores are separately connected to the access controller through a bus, a plurality of software subsystems run on the plurality of processor cores, different software subsystems run on different processor cores, and a power supply of the access controller is different from power supplies of the plurality of processor cores, or the access controller shares a power supply with a first processor core that runs a first software subsystem.
