LPDDR4 DRAM Memory Controller

Developed using Verilog that supports all the key features including various power saving combinations, selective power down for unused DRAM channel(s), different addressing schemes, security, driver, frequency ratios (1:1,1:2,1:4) and many more

LPDDR4 has taken the memory market by a storm owing to the advantages it offers. At Arastu, we target to make the integration of LPDDR4 into your SOCs a smooth one, with the help of our very robust and flexible LPDDR4 DRAM Memory Controller IP. The Design IP supports the popular industry standard AHB/AXI master, however, can be customized as per customer’s requirement. The core is compliant to JEDEC standard JESD209-4B.
