A memory storage apparatus including a memory array and a controller circuit is provided. The memory array is configured to store a first error correcting code and a first data. The controller circuit is coupled to the memory array. The controller circuit is configured to read the first data from the memory array and determine whether an error bit of the first data is one of one or more data mask bits to decide whether to update the first error correcting code stored in the memory array. The controller circuit includes a switch element. The switch element is coupled to the memory array. The switch element receives the first data from the memory array. An error correcting procedure is not performed on the first data. In addition, a data access method is also provided.
