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.

Abstract: Memory systems and methods of operating the memory systems are disclose. In one arrangement, a device includes a memory device configured to store first data, a first input/output (I/O) pin, and a serial communication device configured to receive the first data and output the first data. The serial communication device is connected to the first I/O pin via a first device. The device also includes a virtual communication logic configured to receive the first data and output the first data to a communication interface connected to a host device.
