Abstract
A memory space of a module connected to a memory controller via a memory interface may be used as a command buffer. Commands received by the module via the command buffer are executed by the module. The memory controller may write to the command buffer out-of-order. The memory controller may delay or eliminate writes to the command buffer. Tags associated with commands are used to specify the order commands are executed. A status buffer in the memory space of the module is used to communicate whether commands have been received or executed. Information received via the status buffer can be used as a basis for a determination to re-send commands to the command buffer.
