page length = 2 ^colbit,,
page size in bytes = 2 ^colbits x ORG / 8
where colbits is the number of column address bits and ORG the number of I/O (DQ) bits.

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, (A14) andNC, (A15) are additional address pins for future generation DRAMs
and are not connected on this component.
