Notes:
1) VDDL and VSSDL are power and ground for the DLL.They are isolated on the
device from VDD, VDDQ, VSS and VSSQ.
2) NC, (A13), NC,(A14) and NC,(A15) are additional address pins for future genera-
tion DRAMs and are not connected on this component
3) Ball position G1 “RFU” will be used for BA2 on 1Gbit memory densities and higher
