Memory sub system

[mostafaxx]

peace upon you every one, 

i've a question to ask about the memory (ram)

1-since the cpu can deal with one instruction at a time , how much memory blocks at max can the memory deal with ?

ex: how could the processor with a 16bit data-bus access a 16 bit value which is a 2 places in the ram ?

1. Memory transfer is only 1 instruction at a time too.
2. What do you mean? If what you mean how to access a whole RAM (32-bit pointer) on DOS, you will need to switch the CPU mode to protected mode.
