Abstract
The present disclosure relates to a write-once storage device. In one arrangement, the storage device comprises write-once memory adapted to store data files, re-writable memory that contains a file access table, and a device controller that is configured to control operation of the storage device. In use, the storage device can be used to receive data to be stored from a host device, store the data within write-once memory of the storage device, and update a file access table stored in re-writable memory of the storage device so as to emulate a re-writable storage card.
Claims21
A write-once storage device for use with a host device, comprising:
- write-once memory adapted to store data files;
- re-writable memory that contains a file access table;
- and
- a device controller that is configured to control operation of the storage device such that responsive to the host device attempting to modify the file access table, the controller device enables the file access table contained in the re-writable memory to be modified.
A write-once storage device for use with a host device, comprising:
- write-once memory adapted to store data files;
- re-writable memory that contains a file access table;
- and
- a device controller that is configured to control operation of the storage device;
- wherein the device controller comprises logic that is configured to emulate a re-writable storage device.
A write-once storage device for use with a host device, comprising:
- a plurality of memory layers that comprise write-once memory, the memory layers being arranged in a stacked orientation and adapted to store data files;
- re-writable memory that contains a file access table which holds information about the data files stored in the write-once memory;
- and
- a device controller that controls operation of the storage device, the device controller including logic configured to emulate a re-writable storage device.
A method for manipulating data provided by a host device, comprising:
- receiving data to be stored with a storage device;
- storing data within write-once memory of the storage device;
- and
- updating a file access table stored in re-writable memory of the storage device.
