Abstract:
A method implemented by a non-volatile memory (NVM) controller comprising obtaining a NVM express (NVMe) command comprising a namespace identifier (NSID) from a host memory via a peripheral component interconnect express (PCIe) function, determining a mapping between the PCIe function and a namespace identified by the NSID based on a data structure stored in a PCIe memory address space, and accessing the namespace based on the mapping between the PCIe function and the namespace.
