    Abstract: A memory apparatus and a data rearrangement method for computing in memory (CIM) are provided. The method includes determining whether first sequence data has two target bits that are both of a first value, inserting a non-target bit of a second value between the two target bits that are both of the first value and adjacent to each other to generate second sequence data, and receiving the second sequence data through memory cells in a memory to perform a multiply-accumulate (MAC) operation on the second sequence data. Each bit in the first sequence data is the first value or the second value. One of the two target bits is located adjacent to the other one of the two target bits in the first sequence data. The two target bits and the non-target bit are located in the first sequence data. Accordingly, the error rate is decreased.
