DDR/DDR2 SDRAM Controller MACO Core

The DDR/DDR2 Synchronous Dynamic Random Access Memory (SDRAM) Controller MACO Core is a general-purpose memory controller that interfaces with industry standard DDR/DDR2 SDRAM devices and modules. This IP core is an IPexpress configurable core that provides the flexibility for modifying data widths, burst transfer rates, and CAS latency settings in a design. It provides a simple command interface for application logic. The controller can be configured to function as a DDR only or DDR2 memory controller.

This proven DDR/DDR2 core is optimized utilizing MACO ASIC gates in the LatticeSCM devices, resulting in fast, small cores that utilize the latest architecture to its fullest.

Note the RLDRAM IP Core is implemented using both MACO ASIC gates and soft logic in the FPGA array. Since a significant portion of the implementation is in MACO, more of the FPGA Array is left for the user.
