MEMORY CONTROLLER AND NONVOLATILE STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To much more quickly provide the relocation processing technology of address management information in a nonvolatile storage device based on a relocation type address management method. SOLUTION: The physical address of address management information AT is updated and recorded in a nonvolatile ROM 101. Thus, it is possible to more quickly update and record the address management information AT in a flash memory 104 than a conventional method for updating and recording the physical address of the address management information AT on the flash memory in terms of address management. The guaranteed frequency of the rewriting of the nonvolatile ROM is set so as to be sufficiently larger than the flash memory, (that is, about 10 billion times) so that the rewriting of the physical address of the address management AT on the nonvolatile RAM 101 can be prevented from being problematic in the guaranteed frequency of rewriting.
