rugue Posted October 11, 2014 Report Share Posted October 11, 2014 Hello Guys, I am working on a verilog memory controller and have a question about the actual model of the SDRAM chip, my question comes because the physical chip says that it is a MT48LC4M16A2 from micron (which have 12 pin address bus width), but after checking on papillio pro's hardware guide there is a schematic that says the memory model is a MT48LC64M4A2 (this one have 13 pin address bus width). Also when downloading the generic UCF file from gadget factory website, there are 13 address pins defined there. I was wondering for which memory model should I design? On the other hand, if memory is MT48LC4M16A2 what is the 13th address on the UCF file mapped to? Thank you Quote Link to comment Share on other sites More sharing options...
