    • Disclosed is a storage device using non-volatile semiconductor memory that achieves high performance and long life for the device. When managing the non-volatile semiconductor memory (2), physical blocks are classified into three types: scratch blocks (22), data blocks (23), and erased blocks (24). Data writing from a host device (3) is performed on the scratch blocks. When the number of empty pages within a scratch block becomes less than a predetermined number or no longer exists, the block is treated thereafter as a data block, and one of the erased blocks is newly assigned as a scratch block. If there are insufficient erased blocks, a block with relatively less valid data is selected from among the data blocks. After copying all valid data included in the block to a scratch block, the block is erased, and thus an erased block is acquired.
    • 公开了一种使用非易失性半导体存储器的存储装置,其实现了该装置的高性能和长寿命。 当管理非易失性半导体存储器(2)时,物理块被分为三种类型:暂存块(22),数据块(23)和擦除块(24)。 在暂存块上执行来自主机(3)的数据写入。 当暂存块内的空页数少于预定数量或不再存在时,该块被当作数据块处理,并且其中一个擦除块被新分配为暂存块。 如果擦除块不足,则从数据块中选择具有相对较少有效数据的块。 将块中包含的所有有效数据复制到暂存块后,块被擦除,从而获取被擦除的块。
