A microprocessor with a 16 bit address bus is used in a linear memory selection configuration (i.e., Address bus lines are directly used as chip select of memory chips) with 4 memory chips. The minimum addressable memory space is—
-
- 64 K
- 16 K
- 8 K
- 4 K
Correct Option: A
Each bit require one line so that for n lines, the size of memory in the address bus is 2n
for 16 bit, 216 = 65, 536 or 64 K.
