关于SDRAM地址线，行和列的连接方法，还有下面的资料中，知道的解释一下，谢谢了....
32 bit external bus address mapping (Row, Bank, Column)
1 0 000 00 16 Mb (2Mx8), 2 banks, row length = 11, column length = 9
1 0 000 01 16 Mb (1Mx16), 2 banks, row length = 11, column length = 8
1 0 001 00 64 Mb (8Mx8), 4 banks, row length = 12, column length = 9
1 0 001 01 64 Mb (4Mx16), 4 banks, row length = 12, column length = 8
1 0 001 10 64 Mb (2Mx32), 4 banks, row length = 11, column length = 8
1 0 010 00 128 Mb (16Mx8), 4 banks, row length = 12, column length = 10
1 0 010 01 128 Mb (8Mx16), 4 banks, row length = 12, column length = 9
1 0 010 10 128 Mb (4Mx32), 4 banks, row length = 12, column length = 8
1 0 011 00 256 Mb (32Mx8), 4 banks, row length = 13, column length = 10
