size of memory of computer that uses 16 bits memory address

Question

If the memory address of a computer uses 16 bits, what is the size of its memory? I find many references online but I can't be certain which are relevant. Thank you. 2^16?

Answer 1

From wikipedia:

For instance, a computer said to be "32-bit" also usually allows 32-bit memory addresses; a byte-addressable 32-bit computer can address 2^32 = 4,294,967,296 bytes of memory, or 4 gibibytes (GiB). This seems logical and useful, as it allows one memory address to be efficiently stored in one word.

So to answer your question, in general, yes a 16-bit computer can address 2^16 bytes of memory per word write.
