The pattern of ROM in electric devices

I figured out that the basic storage memory of any electric device has a particular pattern that is:

2 to the power 2, 2 to the power 3, 2 to the power 4, etc...

For example

1GB,

1GB2 =

2GB,

2GB2=

4GB,

4GB2=

8GB,

8GB2=

16GB,

16GB2=

32GB,

32GB2=

64GB,

64GB2=

128GB,

128GB2=

256GB,

256GB2=

512GB,

512GB2=

1TB,
