Multi-chip Package Sequential CAM Read Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-chip memory packages consume high current during the booting process due to simultaneous CAM read operations across multiple memory chips, which is inefficient and increases power consumption.
Innovation Solution
A multi-chip package with a controller that selectively performs CAM read operations by outputting command and address signals to individual memory chips, allowing sequential execution of CAM read operations, reducing simultaneous current consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CAM read operations are performed simultaneously on multiple memory chips during booting, then the booting process can be completed, but the current consumption increases significantly
Solution Approach 1:
The patent divides the simultaneous CAM read operation across multiple memory chips into sequential operations. The controller segments the booting process by performing CAM read operations on each memory chip one after another rather than simultaneously, thereby reducing the peak current consumption while still completing the booting process.
Solution Approach 2:
The controller implements periodic action by alternating between performing CAM read operations on different memory chips. Instead of continuous simultaneous operation, the system activates one chip at a time in a periodic sequence, allowing current consumption to be distributed over time rather than concentrated at once.
2Use of energy by moving object
If CAM read operations are performed sequentially on memory chips, then the current consumption is reduced, but the booting process takes longer
Solution Approach 1:
The controller dynamically manages the booting process by adaptively controlling the timing and sequence of CAM read operations on different memory chips. The system can adjust the operational state of each chip dynamically, enabling flexible optimization between current consumption and booting time based on system requirements.

AI summary
A multi-chip package includes a plurality of memory chips for performing a content addressable memory (CAM) read operation in response to a command signal for the CAM read operation and an address signal for selecting the memory chips and a controller for outputting the command signal and the address signal to the memory chips and controlling the sequence of the CAM read operations for the memory chips.
