How Much Memory Can a Microprocessor with a 12-bit Address Bus Access?

[Muthuraj R]

A microprocessor with 12 bit address bus will be able to access how many kilobytes of memory ??
2^12 = 4096 = 4 kB of memory
Is it right ?
Thanks.

Yes, you are correct. What if it had 16 address lines?

EDIT -- BTW, it is usually written "KB", since k = 1000, and K = 1024.
