Abstract: According to one embodiment, a storage device includes a nonvolatile memory and a controller. The controller manages first user identification information and first authentication information including a hash value calculated from the first user identification information and a first device identification information of a first client device. The controller receives an access request to the nonvolatile memory, user identification information, and authentication information transmitted from an external device, and accepts the access request in a case where the user identification information received matches the first user identification information, and the authentication information received matches the first authentication information.

Abstract: A memory system includes a nonvolatile memory and a controller that controls the nonvolatile memory. The controller is configured to generate information relating to encryption and decryption of data based on a location of the memory system and to enable at least one process of encrypting data to be written to the nonvolatile memory or decrypting data read from the nonvolatile memory by using the information.

Abstract: According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller manages first account information to be used for authentication of a first account and second account information to be used for authentication of a second account. The controller receives third account information from a host device. When the third account information matches the first account information, the controller permits access to at least a partial storage area of the nonvolatile memory based on a request from the host device and transmits first data that includes the second account information to a first memory system.

Abstract: A data processing module includes: a data converter having a TranslateData interface for receiving input data and sending output data, a Property interface for sending and receiving parameter data composed of a character string parameter for Property control, and Open/Close interface for initializing the environment and the state, a query interface for obtaining entries of the internal interfaces of the Open/Close interface, the TranslateData interface, and the Property interface, an API interface for dynamically obtaining by the query interface the four kinds of interfaces of the Open, Close, Property, and TranslateData, and a callback interface designated by the Property interface.

Abstract: A framework registers the entry names of entry interfaces respectively included in modules. The framework acquires operation names (static entries) of operation interfaces included in the module by calling the entry interface based on the entry name. The framework calls the operation interfaces based on the operation names. And the module executes generation of the module itself to be connected to the framework, a process inherent in the module, and deletion of the module itself connected to the framework.

Abstract: A framework for establishing an application system, the framework including: a plurality of data processing modules that is provided with an interface in common with one another, and performs data processing; and a manager module that communicates with the data processing modules via the interface, and controls data transfer between the data processing modules and the data processing performed by each of the data processing modules.

Abstract: A method for processing a microcomputer having a central processing unit detects an interrupt process. The method disrupts a first task under an execution. Then, the method determines the interrupt process and assigns a second task for the interrupt process. The method sets up a second bank for the second task and executes the second task at the second bank. Further more, the method resumes the first task after executing the second task.
