An access method and an access controller for a memory are described. The method includes the following steps: monitoring an actual value of a relevant parameter of a display bandwidth of data to be output by the memory; comparing the actual value of the relevant parameter with a threshold to determine whether the actual display bandwidth meets requirements; and selecting an access arbitration mode for the memory according to whether the requirements are met. The access controller includes: a monitoring and comparing unit, adapted to monitor an actual value of a relevant parameter of a display bandwidth of data to be output by the memory and compare the actual value of the relevant parameter with a threshold to determine whether the actual display bandwidth meets requirements; and an arbitration adjusting unit, adapted to select an access arbitration mode for the memory according to whether the requirements are met. Thus, it is ensured that the display image misalignment does not exist in a display system, and memory access power consumption of the display system is reduced.
