Embodiment Construction

[0024] This manual uses 3D-MPROM (mask-ROM in which memory elements are distributed in a three-dimensional space) as an example to explain mask sharing. The spirit of the invention can be easily extended to the conventional mask-ROM (that is, the memory elements are distributed on the two-dimensional plane mask-ROM). The main method of data entry in Mask-ROM is the printing method. Printing methods include photo-lithography and imprint-lithography (also known as nano-imprint lithography, or NIL for short). Correspondingly, the "mask" in mask programming can be a data mask used by photolithography, or a data template (template, also called master, stamp, or mold) used by imprinting.

[0025] 3D-P is an improved 3D-MPROM, which uses a shared data mask to enter data. image 3 It represents a mask pattern on a shared data mask 18A. Unlike the dedicated data mask 8A in Figure 2, the shared data mask 18A contains 16 different mass publications (MC 1 -MC 16 ) Mask graphics. In this e...

Abstract

High data mask plate cost greatly limits wide application of a three-dimensional mask programmable read-only memory (3D-MPROM). The invention discloses a three-dimensional printed memory (3D-P). The data input cost is reduced by a shared data mask plate. The mask plate cost of each of massive publications is greatly reduced by forming a plurality of data graphs of different massive publications on the same data mask plate.

Description

Technical field [0001] The present invention relates to the field of integrated circuit memory, more specifically, to mask-programmed read-only memory (mask-ROM). Background technique [0002] Optical discs—including DVD discs and Blu-ray Discs (BD)—are the main media for mass publishing. The "mass" in mass publishing has a dual meaning, which refers to the mass distribution of mass publications. Here, each massive publication contains massive amounts of data, and the amount of data is on the order of gigabytes. Its content can be movies, video games, digital maps, music libraries, book libraries, or software. For example, the data volume of a VCD format movie is ~0.5GB, the data volume of a DVD format movie is ~4GB, and the data volume of a BD format movie is ~20GB. On the other hand, mass issuance means that the issuance exceeds 10,000, even reaching the order of one million. [0003] The disc is too large for mobile users. Due to the smaller size of semiconductor memory, it ...
