Embodiment Construction

[0014] Hereinafter, embodiments will be described with reference to the drawings.

[0015] figure 1 The outline shows the storage system according to this embodiment.

[0016] The storage system includes a storage device 11 such as an SD card and a host. The storage device 11 is also called an SD card. In addition, the host 20 is also referred to as a host device. In addition, the storage device 11 does not necessarily need to have a card shape, and may be installed in a manner that cannot be inserted or removed from the host 20.

[0017] The storage device 11 receives power supply and operates when connected to the host 20, and performs processing corresponding to the access from the host 20. The storage device 11 has a card controller 11a.

[0018] The card controller 11a includes, for example, a host interface (I / F) 12, a CPU 13, a ROM (read only memory) 14, a RAM (random access memory) 15, a buffer 16, and a wireless interface (I / F) as an extended function interface ) 17. The...

Abstract

According to one embodiment, a memory system includes an application module, a storage module, and a control module. The storage module stores user data, application software configured to control operation of the application module, and management information used to manage the user data and the application software. The control module controls writing and erasing of the storage module. The control module masks information indicating an access-prohibited area included in the management information read from the storage module, the access-prohibited area includes the application software.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2011-042864 filed on February 28, 2011, and the entire content of the previous application is incorporated herein by reference. Technical field [0002] The present invention relates to a storage system having, for example, a wireless communication function. Background technique [0003] Currently, it is developing storage systems with application modules other than storage functions, such as wireless communication functions such as wireless LAN. The storage system stores user data and application software for controlling the operation of the wireless communication function and / or system software for controlling the operation of the controller in a storage section accessible to the user. Therefore, the user may delete or modify the application software and / or system software stored in the storage unit. Summary of the invention [0004] The embodiments of the present invention provide a storage system ...
