Abstract

A data storage device capable of namespace re-sizing comprises a nonvolatile semiconductor storage device containing data accessed via a logical address that includes a namespace identifier and a logical block address, and a controller. The storage device can convert the namespace identifier to a base address using a first look up table. The storage device can further convert the logical block address to namespace allocation units of storage. The storage device can also determine a pointer using the base address, the namespace allocation units, and a second look up table. Further, the storage device can determine a full logical cluster address using the pointer.
