Ok , creating this trivial driver I can read data from that memory address

It's not a memory address, it's an I/O port.

As Don pointed out, you don't have to write a driver for this. Such
drivers already exist.

I've got the data*** from this hardware monitor chip and the data***
shows which addresses map internally to the three temperature sensors on the
chip .
After reading the address on the ISA Bus , Is it possible to read the
internal memory (internal addresses on the chip ) to read the three
temperature sensors using this trivial driver approach ?

What I still don't get is that I am going to read the value on ISA Bus
memory but after that , how to get to the internal values of the temperature
sensors ?

If you have the data***, then only you can answer these questions. What
you have is access to the I/O ports. If they have a way to access the
internal addresses on the chip through the I/O ports, then you're golden.
