Original Abstract Submitted
a computer storage device having a host interface, a controller, non-volatile storage media, and firmware. the firmware instructs the controller to: generate mapping data defining mapping, from logical block addresses in namespaces configured on the non-volatile storage media, to logical block addresses in a capacity of the non-volatile storage media; maintain an active copy of the mapping data; generate cached copies of the mapping data from the active copy; generate a shadow copy from the active copy; implement changes in the shadow copy; after the changes are made in the shadow copy, activate the shadow copy and simultaneously deactivate the previously active copy; and update the cached copies according to the newly activated copy, as a response to the change in active copy identification.
