Abstract
An apparatus () causes invalid data to be read again from a memory device () before being read by a device (). A transaction queue () stores pending and dispatched device transactions, the queue includes an input for receiving () transactions, an output for dispatching () transactions, a pointer for pending transactions, and a pointer for dispatched transactions. A master controller () responds to an invalid data signal by preventing the transaction queue from dispatching pending transactions to the memory device, by causing the transaction queue to dispatch again the device read transaction which resulted in the invalid data and, subsequently, by causing the data which was read again from the memory device to be accepted by the destination device, by setting the dispatched transaction pointer to the pending transactions pointer, and by enabling the transaction queue to dispatch pending transactions to the memory device.
