Memory (KB)64.0 KB
Memory (MB)0.06 MB
Addressable Locations65,536
Total Addressable Memory vs Address Bus Width (bits)
Memory Address Space
The address bus width determines how many unique memory locations a processor can access.
Formula
Locations = 2^Address_Bits
Total Memory = Locations x (Data_Bus_Width / 8) bytes
Common Examples
Example Calculation
16-bit address bus with 8-bit data bus.
- 01Locations: 2^16 = 65,536
- 02Bytes per location: 8/8 = 1
- 03Total: 65,536 x 1 = 65,536 bytes
- 04In KB: 65,536 / 1024 = 64 KB
