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.
