Abstract

The paper presents the implementation of compliant DDR3 memory controller. It discusses the overall architecture of the DDR3 controller along with the detailed design and operation of its individual sub blocks, the pipelining implemented in the design to increase the design throughput. It also discusses the advantages of DDR3 memories over DDR2 memories operation. Double Data Rate (DDR) SDRAMs have been prevalent in the PC memory market in recent years and are widely used for networking systems. These memory devices are rapidly developing, with high density, high memory bandwidth and low device cost. However, because of the high-speed interface technology and complex instruction-based memory access control, a specific purpose memory controller is necessary for optimizing the memory access trade off. In this paper, a specific purpose DDR3 controller for highperformance is proposed.
