    • An allocation method comprises: partitioning moderate memory into a plurality of physical memory pages having predetermined page size according to the predetermined page size; scanning the moderate memory using the predetermined page size and recording the physical address and damage degree of each physical memory page; obtaining the allocation information of the physical memory pages when a memory request is received and allocating physical memory to the request based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information. A moderate memory is scanned and the physical address and damage degree of each physical memory page are recorded, then the physical memory is allocated based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information.

    • A method for managing blocks in a flash memory is provided, which includes dynamic and static block managing methods. In the dynamic block managing method, a blank block is selected as a swap block for write operation. During each write operation, new data and/or original data in an object block to be operated are written into the swap block, and the object block is erased. Then, a logical address of the object block is changed to be a logical address of the swap block, so that the object block served as the swap block for a next write operation. In the static block managing method, a variable seed parameter is set. Different values of the seed parameter are each associated with a logical address of a respective flash memory block. When the value of the seed parameter varies, data in the flash memory block and the swap block associated to the value of the seed parameter are exchanged, so that the flash memory block associated to the value of the seed parameter becomes the swap block for the next write operation.
    • 提供了一种用于管理闪存中的块的方法,其包括动态和静态块管理方法。 在动态块管理方法中,选择空白块作为写操作的交换块。 在每个写入操作期间,将要操作的对象块中的新数据和/或原始数据写入交换块,并且擦除对象块。 然后,将对象块的逻辑地址改变为交换块的逻辑地址,使得对象块用作下一个写入操作的交换块。 在静态块管理方法中,设置变量种子参数。 种子参数的不同值各自与相应闪存块的逻辑地址相关联。 当种子参数的值变化时,交换闪存块和与种子参数的值相关联的交换块中的数据,使得与种子参数的值相关联的闪存块成为用于 下一个写操作。
