Abstract
A solid state drive (SSD) and a method for managing data stored in the SSD is disclosed. In one embodiment, the SSD includes a memory controller and a controller memory buffer within the memory controller. The SSD further includes a host interface communicatively coupled to the memory controller and configured to receive a set of host commands from a host device. A first local processor of the SSD is configured to generate a set of local commands, and a second local processor of the SSD is configured to execute the set of local commands and the set of host commands. The memory controller is configured to store the set of local commands in a first area of the controller memory buffer reserved for the first local processor and to store the set of host commands in a second area of the controller memory buffer reserved for the host device.
