Abstract
A technique for sharing resources in a data storage device. The data storage device receives a command associated with a non-volatile semiconductor memory device from a host system, the command including a virtual function identifier and a transaction identifier. The data storage device identifies, via a virtual function mapping unit that is included within a controller and that maintains a function mapping table which stores programmable values that associate virtual functions with portions of shared resources of the controller, a portion of a shared resource of the controller based on the virtual function identifier and the transaction identifier. The data storage device accesses the identified portion of the shared resource based on the received command.
