In main memory, the access time (sometimes response time) is the time period between the start of a read access cycle, and the point in time when the data is returned to the requestor.
In DRAM memories, if the memory is in the middle of a refresh cycle when the request arrives, that can delay the memory's response - and thus the access time for that particular cycle.
