Abstract:
A system and method to transfer an ordered partial store of data from a controller to a memory subsystem receives the ordered partial store of data into a buffer of the controller. The method also includes issuing a preinstall command to the memory subsystem, wherein the preinstall command indicates that data from a number of addresses of memory corresponding with a target memory location be obtained in local memory of the memory subsystem along with ownership of the data for subsequent use. A query command is issued to the memory subsystem. The query command requests an indication from the memory subsystem that the memory subsystem is ready to receive and correctly serialize the ordered partial store of data. The ordered partial store of data is transferred from the controller to the memory subsystem.
