  • Patent number: 11923004
    Abstract: A system and method of storing and reading digital data, including providing a nanopore polymer memory (NPM) device having at least one memory cell comprising at least two addition chambers each arranged to add a unique chemical construct (or codes) to a polymer (or DNA) string when the polymer enters the respective addition chamber, the data comprising a series of codes; successively steering the polymer from deblock chambers through the nanopore into the addition chambers to add codes to the polymer to create the digital data pattern on the polymer; and accurately controlling the bit rate of the polymer using a servo controller. The device may have loading chamber(s) to load (or remove) the polymer into/from the deblock chambers through at least one “micro-hole”. The cell may be part of a memory system that stores and retrieves “raw” data and allows for remote retrieval and conversion. The cell may store multi-bit data having a plurality of states for the codes.
