GOWIN DDR3 MEMORY INTERFACE

 

The Gowin DDR3 Memory Interface IP is an IP that is generally used for DDR3, which conforms to the JESD79-2F standard protocol. The IP includes the DDR3 memory controller (MC) and the corresponding physical interface (PHY) design. The Gowin DDR3 Memory Interface IP provides you with a generic command interface through which you can connect with the memory chip to access and save data.
