A system-in-package (SIP) module that integrates a cache memory, a memory controller, and a memory on a shared semiconductor chip, with the memory controller and cache memory formed on the same chip, allowing for optimized performance, efficiency, and cost by customizing the module to respond to various memories and logic integrated circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard memory designs are used with memory controllers communicating with various different standard memories, then compatibility with different memory types is achieved, but performance, efficiency, and cost are suboptimal
Solution Approach 1:
The memory controller is integrated directly into the semiconductor memory device, allowing the same memory device to serve multiple functions and different applications without requiring external memory controllers. This integration enables the memory device to be universally applicable across different systems while optimizing performance for each specific use case.
Solution Approach 2:
The patent combines the memory controller and memory device into a single integrated semiconductor device. This merging eliminates the need for separate external controllers and reduces the number of components, thereby improving performance, efficiency, and cost-effectiveness while maintaining compatibility with different memory types.
2Adaptability or versatility
If memory controllers are designed to respond to various different standard memories, then versatility is improved, but device complexity increases
Solution Approach 1:
By integrating the memory controller directly into the semiconductor memory device, the patent reduces overall system complexity. The controller and memory become a single unified component, eliminating the need for complex external controller designs and reducing the number of interconnections required.
Solution Approach 2:
The integrated memory controller is designed to handle multiple memory types and protocols within a single device, reducing the need for multiple specialized controllers. This multi-functional approach simplifies the overall system architecture while maintaining versatility.
3Productivity
If SIP modules integrate application logic ICs, known good die memories, and memory controllers, then system performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the memory controller and memory device into a single semiconductor device that can be manufactured as one unit. This integration simplifies the SIP module assembly process by reducing the number of separate components that need to be packaged and interconnected, thereby improving ease of manufacture while maintaining high system performance.

AI summary
A system-in-package module with memory includes a non-memory chip, a substrate, and a memory chip. The non-memory chip has a first portion and a second portion. The substrate has a window and the substrate is electrically connected to the second portion of the non-memory chip. The memory chip is placed into the window of the substrate to electrically connect the first portion of the non-memory chip, and there is no direct metal connection between the memory chip and the substrate.
