1. Suppose the memory address in an embedded system has 12 bits. How many unique memory locations can this 12-bit address access
const2013 [10]

Answer:

14 bits memory address - 4096 bits.

16 bits memory address - 16384 bits.

Explanation:

The computer system memory is a hardware component that provides the necessary memory space and location to run software application on the computer system. The memory address location comes in various sizes.

A 14 bit memory can address 2^14 bits which is 4096 bits, since each 14 bit line carries a bit on which line. So for a 16 bit memory address, 2^16 bits location is addressed.
