Hai,
I have a doubt on 8051 micro-controller, i.e for 8051 micro-controller max code memory will be 64k and max data memory is 64k.So how we are going access this both 64k memory of code memory and 64k memory of data memory using 16 address lines in 8051.

Ah - re-reading the original post, I think you may well be right!
In which case, yes: there are not just 16 address lines - there are also distinct read/write control lines.
And, as you say, the so-called "bible" describes this fully.
