MIG 7 Series and Virtex-6 MIG DDR2/DDR3 Solution Center Design Assistant - Controller Architecture Design

Description

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). This section of the MIG 7 Series and Virtex-6 FPGA Design Assistant focuses on the architecture design of the DDR2/DDR3 MC. Please select from the options below for information related to your specific question.
