摘要： There is provided a management device including a management unit that manages a nonvolatile memory configured to allow data to be written, read, or erased electrically, allow writing and reading to be performed in units of a page, and allow erasing to be performed in units of a block including a plurality of pages. The management unit divides a plurality of physical blocks of the nonvolatile memory into a virtual area including virtual blocks corresponding to the physical blocks, and an alternate area including alternate blocks for replacing defective physical blocks in the virtual area, manages the nonvolatile memory in management units of three stages including management of the physical blocks, management of the virtual blocks, and management of extended blocks, and writes to the nonvolatile memory first, second, and third management information for use in the management of the physical blocks, the virtual blocks, and the extended blocks, respectively.

摘要： An administration device includes an administration section. The administration section administers writing, reading, and erasing of data in a nonvolatile memory, in which the data can be electrically written, read, and erased and the writing and the reading are performed on a page-by-page basis and the erasing is performed on a block-by-block basis, by translating a logical address into a physical address on a per translation unit basis; and performs fold processing of increasing unwritten physical translation units by the number of written invalid physical translation units, which are contained in a block of a copy source, by copying data of written valid physical translation units among the contents of the block into a block, in which the unwritten physical translation units reside, and by erasing the block of the copy source.
摘要翻译：管理装置包括管理部。管理部分管理非易失性存储器中的数据的写入，读取和擦除，其中可以电子写入，读取和擦除数据，并且逐页地执行写入和读取，并且擦除是通过在每个翻译单元的基础上将逻辑地址翻译成物理地址来逐块执行; 并且通过将包含在复制源的块中的写入的无效物理转换单元的数量，通过将块中的所写入的有效物理转换单元的数据复制到块中来执行增加未写入物理转换单元的折叠处理，其中未写入的物理转换单元驻留，并且通过擦除复制源的块。
