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.
Claims20
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.
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 the steps of:
- 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.
