Abstract: A memory system includes a memory controller and a memory component coupled to each other. An interface of the memory component is configured to receive a first signal from the memory controller with read request information, retrieve the read data information from the memory core in response to the request information, and transmit to the memory controller a second signal containing the read data information. The read data information includes read data symbols, where the average duration of the read data symbols, measured at the interface, defines a symbol time interval. A first external access time is measured at the interface between a first read request and read data transmitted by the interface in response to the first read request. A second external access time interval is measured at the interface between a second read request and read data transmitted by the interface in response to the second read request.
