NONVOLATILE STORAGE DEVICE, HOST DEVICE, NONVOLATILE STORAGE SYSTEM, DATA RECORDING METHOD, AND PROGRAM

摘要

Provided are a memory controller, a nonvolatile storage device, a host device, and a nonvolatile storage system which can perform real-time recording even when alternately performing write-in of normal data and write-in of file management information and additional information.  A host device (2) issues a memory management command before start of a real-time recording or after end of the real-time recording or at the both timings.  When the nonvolatile storage device (1) receives a memory management command, a memory controller (11) arranged inside clears the memory control information and performs garbage collection if necessary.
