The Memory Controller Block (MCB) is responsible for receiving all requests from the User Interface.In processing these requests, the MCB ensures that all functional and timing requirements of the JEDEC standard/memory device are met. The MCB only receives Read/Write commands, but must ensure that all required commands to complete Reads/Writes are sent (Refresh, Activate, Precharge).
