A data access controller and data accessing method is provided. The data access controller includes: a flash memory configuration register unit for storing information used for data access in a flash memory; a flash memory control unit for generating a control signal for data access to a block and a page in the flash memory according to the information used for data access stored in the flash memory configuration register unit; and a temporary memory control unit under the control of the flash memory control unit, adapted to generate a control signal for temporary storage of data. In the inventive solution, data access in the flash memory is under the control of the data access controller, thereby reducing CPU workload, improving operation speed and generality of the control on the data access in flash memory by storing the information for data access for at least one type of flash memory.
