HOW CAN ADDRESSING MORE OF 32K RAM ON 8031/51 MICRO?
FOR EXAMPLE 128K OR 256k

Memory paging.
It is an old and well used method. Supported by all 8x51 popular compilers.
 

it is more than 64k exactly.
you may wire P1 to A16,A17....
in software,you must set correct A16 A17....,then you may use movx etc
 

Hi

For 8051, paging is called "memory banking". Try a search on G00gle with these key words.
