Three-dimensional offset-printed memory with multiple bits-per-cell
View Patent ↗The present invention discloses a three-dimensional offset-printed memory (3D-oP) with multiple bits-per-cell. The mask-patterns for different bits-in-a-cell are merged onto a same data-mask. At different printing steps, a wafer is offset by different values with respect to the data-mask. Accordingly, data-patterns from a same data-mask are printed into different bits-in-a-cell.
