Systems and methods for acoustic wave enabled data storage

摘要

The present disclosure provides systems and methods for storing, reading, and writing data using particle-based acoustic wave driven shift registers. The shift registers may physically shift particles along rows and/or columns of wells through the interactions of two parallel surfaces. A transducer may generate an acoustic wave to displace one or more of the two parallel surfaces. The particles may be transferred to and/or otherwise constrained by a buffer surface during at least a portion of the acoustic wave, such that the particles may be shifted during one or more cycles of the acoustic wave. In various embodiments, the amplitude of the acoustic wave may correspond to the spacing distance between each of the wells. The wells may be physical and/or potential wells.

主权项

1. A memory array, comprising:
a plurality of particles; a plurality of sets wells uniformly spaced by a spacing distance along a longitudinal axis of a first surface, wherein each of the plurality of sets of wells is configured to selectively retain at least one set of the plurality of particles; a buffer surface positioned substantially parallel to the first surface, the buffer surface configured to selectively retain the plurality of particles; a transfer unit configured to selectively modify a characteristic of the memory array to transfer at least some of the plurality of particles between the first surface and the buffer surface; and an acoustic wave transducer configured to selectively generate an acoustic wave to displace one or more of the buffer surface and the first surface and associated wells along the longitudinal axis by at least one half of the spacing distance relative to the buffer surface at a peak amplitude of the acoustic wave.
