Abstract: A solid state storage device including a non-volatile memory Express (NVMe) controller and configured to manage a Host Memory Buffer (HMB) in a host may be provided. The NVMe controller may be configured to fetch HMB descriptor entries as part of a feature command from the host, partition the HMB logically into a control buffer partition and a data buffer partition, store the HMB descriptor entries pointing to the control buffer partition within the solid state storage device as an HMB pointer list table, and write-back the HMB descriptor entries pointing to the data buffer partition into the control buffer partition of HMB.
