A system and method for managing multiple file systems on a single non-volatile memory system is described. The system may include a non-volatile memory system with non-volatile memory having first and second file systems, each associated with respective files, and having a common pool of free space. The controller may be configured to update a file system to be mounted to reflect a capacity relating to only the respective files for that file system and all of the common pool of free space, while hiding from the host the file system not being mounted. The method may include the controller only presenting a single file system and hiding the unmounted file system, or may include the controller managing multiple file systems by presenting multiple file systems concurrently.

System and method for managing multiple file systems in a memory

A storage module, host, and method for securing data with application information are disclosed. In one embodiment, a storage module is provided comprising a memory and a controller. The controller is configured to store data and information about an application that generated the data and allow the data to be read only if information about an application attempting to read the data matches the information about the application that generated the data. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Storage module, host, and method for securing data with application information

A non-volatile storage system comprises a controller and one or more memory die in communication with the controller. The controller sends data and an initial address in conjunction with a request to program the data to one of the memory die. The memory die comprises a plurality of non-volatile storage elements and one or more control circuits. The one or more control circuits attempt to program the data to the non-volatile storage elements at the initial address and determine that programming of the data at the initial address fails. The one or more managing circuits automatically identify a new address in the memory die without the memory die being instructed of the new address by the controller and program the data at the new address on the memory die without the data being re-transmitted from the controller to the memory die.
