how to access row in ddr
I have to design an interface to DDR SDRAM controller such that to access a 1GB i required 30 bits , but when I checked IP CORE it has only 28 bit address for the 32 bit data from user side. moreover byte enables are 4.
my doubt is
1.how to convert the 30 bit address to 28 bit.
2.CAN we access by removing LSB bits and doing some logic with Byte Enables
Give ur ideas please
