描述

This section of the MIG Design Assistant focuses on the Controller Responsibilities of the MIG 7 series andVirtex-6 DDR3/DDR2 designs. The Memory Controller (MC) is responsible for receiving all requests from the User/Native Interface and storing them in a logical queue.In processing these requests, the MC ensures that all functional and timing requirements of the JEDEC standard/memory device are met. The MC only receives Read/Write commands, but must ensure that all required commands to complete Reads/Writes are sent (Refresh, Activate, Precharge).
