    • An architecture for a mass storage system using flash memory involves organizing the flash memory into a plurality of blocks which are then divided into several categories (181-183, 172-174, 177-176). There are three categories of blocks: 1) working category (172-174) used to store data organized in accordance with a pre-defined addressing scheme (such as the logical block address used in Microsoft's operating system), 2) temporary buffer used to store data intended to be written to one of the working blocks (176), and 3) blocks that need to be erased (181-183). When data is written into the mass storage system, a block in the second category (176) is allocated from a block in the third category (181-183). The allocated block will then be changed to a block in the first category when writing to the allocated block is completed (172-174). The corresponding block in the first category is placed into the third category (e.g. 172).
    • 使用闪速存储器的大容量存储系统的架构涉及将闪存组织成多个块,然后将这些块分成几个类别(181-183,172-174,177-176)。 有三种类型的块:1)用于存储根据预定义寻址方案(例如Microsoft操作系统中使用的逻辑块地址)组织的数据的工作类别(172-174),2)用于 存储要写入其中一个工作块(176)的数据,以及3)需要擦除的块(181-183)。 当数据被写入大容量存储系统时,第二类别(176)中的块从第三类别(181-183)中的块分配。 然后,当写入分配的块完成时,分配的块将被改变为第一类中的块(172-174)。 第一类别中的相应块被放置在第三类(例如172)中。
