HI venkatesh,
i am sorry.. actually i my code is like that only, what you said..
i simply write the concept..
my code is like this:

mov dptr,#3236h
mov a,#01h
movx @dptr, a

But that is not my question ??
i am able to write into all locations of my SRAM. But at the time of reading it is giving me some garbage?

is there any chance to time delay problem?

otherewise what it should be?

pls mail me..
regards
