Method and device for storing information in molecule

A method for storing information in a molecule, comprising:

• obtaining initial information to be stored, and representing the initial information using a first address code and a first content code, wherein each position in the initial information is represented by a first address code one-to-one corresponding to the position respectively, and a content at each position of the initial information is represented by a respective first content code respectively;
• recoding each first address code respectively, to represent one respective first address code using first recoding information with a first preset bit number and a first preset base;
• determining respective molecular modules according to the first content code and the first recoding information;
• and
• combining the determined molecular modules in order, such that a composition corresponds to the initial information.
