Abstract
The present invention discloses a three-dimensional writable printed memory (3D-wP). It comprises at least a printed memory array and a writable memory array. The printed memory array stores contents data, which are recorded with a printing means; the writable memory array stores custom data, which are recorded with a writing means. The writing means is preferably direct-write lithography. To maintain manufacturing throughput, the total amount of custom data should be less than 1% of the total amount of content data.
Claims9
A method of making a three-dimensional writable printed memory (3D-wP), comprising the steps of:
- 1) forming a substrate circuit on a semiconductor substrate;
- 2) recording custom data using a direct-write lithography;
- 3) recording content data into a plurality of vertically stacked memory levels above said substrate using a printing means, wherein said memory levels are stacked above and coupled to said substrate;
- wherein the total amount of said custom data is less than 1% of the total amount of said content data.
