LPDDR4 DRAM Memory Controller

lpddr4-controller-new2
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.
