LPDDR3 DRAM Memory Controller

Fully compliant to JEDEC standard JESD209-3C. The Controller supports the popular industry standard AHB/AXI master, however, can be customized as per customer’s requirement.

Increased Bandwidth, Low Power Consumption, Extended Battery Life are some of the advantages the LPDDR3 DRAM offers in contrast to predecessors. At Arastu, we have developed a highly flexible and configurable design for LPDDR3 DRAM Memory Controller. The design IP supports the industry standard AHB/AXI, however, can be customized as per customer’s requirement. The controller is optimized for ASIC and FPGA designs.
