How many memory locations can an 8-bit address bus access?
Think about how many combinations 8 bits create.
What is the main characteristic of ROM?
Consider what happens to data when power is off.
What is the maximum number of memory locations an 10-bit address bus can access?
Recall the powers of 2 related to address buses.
True or False: All types of ROM are volatile.
Consider if ROM retains data without power.
Design a simple digital device using both RAM and ROM and calculate the required size of the address bus for 8 GB of RAM and 2 GB of ROM.
Remember to calculate the total address lines needed for maximum access to each memory type.
If a computer operates on a 128-bit address bus and you want to estimate how many memory locations it can access. Provide your calculations.
Use the exponential formula for powers of 2.
