Benefits of technology
The present invention is a processor for enhancing network security. It uses a three-dimensional (3-D) integration of pattern-processing circuits and memory circuits, which are stacked on top of each other. The permanent and in-situ nature of the stored patterns in the processor improves network-security performance. The 3-D integration offers many benefits, including more storage capacity and more processing power, resulting in a smaller footprint and lower overall cost. The connections between the memory circuits and processing circuits are short and numerous, leading to a larger bandwidth. Overall, the processor improves network security by performing pattern matching or processing on network packets against rule / virus patterns.
Problems solved by technology
Unfortunately, a conventional network-security system cannot meet these requirements.
Furthermore, because the processor is separated from the storage in a von Neumann architecture, the “memory wall” between them would cause a long delay when the processor fetches rule / virus patterns from the storage.
As a result, the performance of the conventional network-security system is poor.

Embodiment Construction
[0027]Those of ordinary skills in the art will realize that the following description of the present invention is illustrative only and is not intended to be in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons from an examination of the within disclosure.
[0028]Referring now to FIG. 1, a preferred processor 200 for enhancing network security, i.e. a three-dimensional (3-D) security processor, is disclosed. The preferred 3-D security processor 200 not only performs pattern processing, but also permanently stores a rule / virus database. It comprises m×n storage-processing units (SPU) 100aa-100mn. Each SPU is commutatively coupled with an input 110 and an output 120. The input 110 includes at least a network packet, while the output 120 includes at least a result of the pattern processing. Storing rule / virus patterns permanently and in situ, the preferred 3-D security processor 200 avoids the “memory-wall” faced by the von Neuma...

To achieve a better overall performance, a preferred pattern processor offsets large latency with massive parallelism. It comprises a plurality of storage-processing units (SPU's), each of which comprises a single pattern-processing circuit, at least a three-dimensional memory (3D-M) array and a plurality of inter-storage-processor (ISP) connections. The ISP-connections do not penetrate through any semiconductor substrate.
