    Abstract: An operating method of a storage device is provided. The operating method comprises the following steps. First, a first data is read from a target address of a first storage unit. Then, an assisting unit checks whether the target address is corresponding to a second data stored in a second storage unit. If the target address is corresponding to the second data, the assisting unit updates the first data according to the second data to generate an updated data. Next, an Error Correction Code (ECC) performs a decoding process on the updated data to generate a decoded data.

    Abstract translation: 提供了一种存储装置的操作方法。 操作方法包括以下步骤。 首先,从第一存储单元的目标地址读取第一数据。 然后,辅助单元检查目标地址是否对应于存储在第二存储单元中的第二数据。 如果目标地址对应于第二数据,则辅助单元根据第二数据更新第一数据以产生更新的数据。 接下来,纠错码(ECC)对更新后的数据进行解码处理,生成译码后的数据。

    Abstract: A method is provided for managing a memory device including a plurality of physical memory segments. A logical memory space is classified into a plurality of classifications based on usage specifications. The plurality of physical memory segments is allocated to corresponding logical addresses based on the plurality of classifications, and on usage statistics of the physical memory segments. A data structure is maintained recording translation between logical addresses in the logical memory space and physical addresses of the physical memory segments. The plurality of classifications includes a first classification and a second classification having different usage statistic requirements than the first classification. Logical addresses having the second classification can be redirected to physical segments allocated to logical addresses having the first classification, and the data structure can be updated to record redirected logical addresses. A free command can release a physical memory segment allocated for main memory use.

    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: A method is provided for managing a file system including data objects. The data objects, indirect pointers and source pointers are stored in containers that have addresses and include addressable units of a memory. The objects are mapped to addresses for corresponding containers. The indirect pointer in a particular container points to the address of a container in which the corresponding object is stored. The source pointer in the particular container points to the address of the container to which the object in the particular container is mapped. An object in a first container is moved to a second container. The source pointer in the first container is used to find a third container to which the object is mapped. The indirect pointer in the third container is updated to point to the second container. The source pointer in the second container is updated to point to the third container.

    Abstract: A computation method and a computation apparatus exploiting weight sparsity, adapted for a processor to perform multiply-and-accumulate operations on a memory including multiple input and output lines crossing each other. In the method, weights are mapped to the cells of each operation unit (OU) in the memory. The rows of the cells of each OU are compressed by removing at least one row of the cells each mapped with a weight of 0, and an index including values each indicating a distance between every two rows of the cells including at least one cell mapped with a non-zero weight for each OU is encoded. Inputs are inputted to the input lines corresponding to the rows of each OU excluding the rows of the cells with the weight of 0 according to the index and outputs are sensed from the output lines corresponding to the OU to compute a computation result.
