LPDDR3/4 DRAM Memory Controller

LPDDR3-4-Controller
SoC designers who are planning to run the design at multiple speeds can leverage Arastu Systems’ LPDDR3/4 IP core and will have the benefit of supporting wide range of system application using the same design...

High-end computing applications requires Higher Performance keeping the Power and Latency intact. On customer demand, after successful implementation of LPDDR4 Memory Controller, Arastu Systems have developed a LPDDR3/4 DRAM Memory Controller in order to support wide range of application using the same design. 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.
