External memory

USBS6 offers the opportunity to use various external memory architectures in one´s FPGA design. With Micron Technology MT46H64M16LFCK-5 up to 1Gbit of high-speed low- power DDR SDRAM is available. The integrated memory controller of Spartan-6TMdevices enables system designers to implement state-of-the-art memory interfaces without the need to develop a whole memory controller Soft-IP all on their own. Some examples on how to implement LPDDR with Spartan-6 are available in chapter C.

the column address and auto precharge bit (A10) for READ or
