    Abstract: A data management method for memory and a memory apparatus are provided. The memory includes a number of memory pages. Each of the memory pages includes multiple memory cells. Each of the memory cells includes a first bit and a second bit. Each of the memory cells has a first logical state, a second logical state, a third logical state, and a fourth logical state. The data management method for memory includes the following steps. A data update command corresponding to a logical address is received. The logical address corresponds to a physical address before receiving the data update command. A sanitizing voltage is applied to a first target memory cell of the memory cells in a target memory page of the memory pages located at the physical address. The logical state of the first target memory cell is changed.

    Abstract: Technology is described that supports reduced program disturb of nonvolatile memory. A three/two dimensional NAND array includes a plurality of pages, which are divided into a plurality of page groups. Access is allowed to memory cells within a first page group of a plurality of page groups in an erase block of the three dimensional NAND array, while access is minimized to memory cells within a second page group of the plurality of page groups in the erase block of the three/two dimensional NAND array. Pages in the same page group are physically nonadjacent with each other in the three/two dimensional NAND array.

    Abstract: An in-memory computing method and an in-memory computing apparatus are adapted to perform multiply-accumulate (MAC) operations on a memory by a processor. In the method, a pre-processing operation is respectively performed on input data and weight data to be written into input lines and memory cells of the memory to divide the input data and weight data into a primary portion and a secondary portion. The input data and the weight data divided into the primary portion and the secondary portion are written into the input lines and the memory cells in batches to perform the MAC operations and obtain a plurality of computation results. According to a numeric value of each of the computation results, the computation results are filtered. According to the portions to which the computation results correspond, a post-processing operation is performed on the filtered computation results to obtain output data.

    Abstract: A data management method for a memory is provided. The memory includes memory pages. Each of the memory pages includes memory cells. A data update command corresponding to a logical address is received. The logical address maps to a physical address of a target memory page before receiving the data update command. First and second reading voltages are applied to obtain at least a first and a second target memory cell to be sanitized in the target memory page of the memory pages, a first programming voltage is applied to change the logical state of the first target memory cell to a logical state with a higher threshold voltage, and a second programming voltage is applied to change the logical state of the second target memory cell to a logical state with a higher threshold voltage. The first programming voltage is different from the second programming voltage.
