Abstract
A system and method for controlling data access in a memory system is disclosed. The memory system is characterized by the use of a transport and retire write request, memory devices incorporating a retire buffer, and inherent data retirement. Addresses associated with un-retired write data are stored in the memory controller and compared to the address of a read request following one or more write requests. Where a read request is directed to an address associated with an un-retired write data, the read request is stalled in the memory controller.
