It can access 64k mem locations in RAM
Generally memmory refers to RAM

u can access both depends on the memory arrangement
A typical memory map might be:
EPROM: 0x0000-0x7FFF, 16 bit non-multiplexed
RAM: 0x8000-0xBFFF, 16 bit non-multiplexed
IO: 0xC000-0xF9FF, 8 bit muliplexed
RAM: 0x10000-0x3FFFF, 16 bit non-multiplexed
Of course, such a complicated map is not strictly necessary and is only given as an example!
In some systems, the CPU can have RAM at zero: all variants have a bootstrap loader built-in which can receive an application program via the serial port. This is often used to program FLASH EPROM during field program updates
I will really suggest if u can get of Computer Systems Architecture book by Morris Mano that one of the best books in world on your query ...

hmm. I don't know what you are asking. But it will take four read or write cycles for a 16 bit bus to access 64k of memory. This is usually in the RAM of a computer.

RAM or ROM can be "mapped" anywhere in the 64k address space. In modern computers, I believe this mapping is done by the MMU. In older computers like the Commodore 64, this was done with logic chips (and, or, xor, etc.) or a programmable logic chip (PAL or GAL usually).
Edit: Oops...why did I say 16k? I must have had that "Hey, Hey 16k" song stuck in my head
