Home› Applications› Capacity & Address‐Line Calculator
When designing a Memory Module, you often need to know exactly how many address lines you’ll require for a given capacity—or conversely, what total capacity is achievable with your chosen address width. This Capacity & Address‐Line Calculator lets you input either the number of address bits or the desired capacity (in MB/GB) and instantly see the corresponding value. It’s ideal for engineers sizing DRAM arrays, onboarding new Memory Module form factors, or verifying compatibility in early‐stage schematics.
Enter the number of address lines to calculate the approximate memory capacity in megabytes (MB).
Note: Capacity ≈ 2n bytes ≈ value/1,048,576 MB
This tool calculates memory capacity in megabytes based on the number of address lines you enter.
How many address lines can I input?You can input any positive integer. The higher the number, the greater the memory capacity.
Why convert bytes to megabytes?Megabytes (MB) provide a more readable unit when dealing with large memory sizes.
Can I use this on mobile devices?Yes, the calculator is responsive and works on modern mobile and desktop browsers.
How accurate is the result?Results are based on 1 MB = 1,048,576 bytes (220), which is standard in computing.
