Abstract: In a particular embodiment, a storage device with a memory, a controller, and a host interface has a write-once read-many device configuration. The memory contains a database having entries, each entry for a logical memory address. The memory further contains information for converting each logical memory address to a redirected logical memory address that corresponds to a physical memory location. The controller receives a command specifying a logical memory address and interprets the command based on information extracted from the database. The controller executes the command according to the information.

Abstract: A storage device with a memory, a controller, and a host interface, and a method of handling commands in a storage device are provided to execute commands in a storage device having a write-once read-many device configuration, transparently to a host device. The memory containing a database having entries each entry for a logical memory address and containing information for converting that logical memory address to a redirected logical memory address that represents a memory location where data associated with that logical memory address actually resides. The controller performs, when the host interface is operatively coupled to a host device, to receive a command specifying a logical memory address and interpret the command based on information extracted from the database. The controller executes the command according to the information, transparently to the host device.
