Transaction management based on metadata

An apparatus, comprising:

• a host device coupled with an interface controller and operable to:
• transmit a read command to the interface controller;
• receive a set of data from the interface controller based at least in part on the read command;
• receive an indication of a request status for the set of data, the request status indicating whether the set of data was requested by the host device;
• and
• process the set of data based at least in part on the request status for the set of data.

An apparatus, comprising:

• first logic coupled with a first bus interface that is configured to interface with a command and address bus, the first logic configured to issue a read command to an interface controller via the command and address bus;
• storage coupled with a second bus interface that is configured to interface with a data bus, the storage configured to receive a set of data over the data bus and store information associated with the read command issued to the interface controller by the first logic;
• and
• second logic coupled with the storage, the second logic configured to match the read command with a received set of data based at least in part on the information associated with the read command and metadata received with the set of data.
