Abstract
A controller device and an operation method for a non-volatile memory with 3-dimensional architecture are provided. The controller device includes an error checking and correcting (ECC) circuit and a controller. The controller is coupled to the non-volatile memory and the ECC circuit. The controller may access a target wordline of the non-volatile memory in accordance with a physical address. The controller groups a plurality of wordlines of the non-volatile memory into a plurality of wordline groups, wherein different wordline groups have different codeword structures. The controller controls the ECC circuit according to the codeword structure of the wordline group of the target wordline, and the ECC circuit generates a codeword to be stored in the target wordline or check a codeword from the target wordline under control of the controller.
