Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory device stores operation setting information for multiple operation types simultaneously in cache memory, then all operation types can be executed efficiently, but the cache memory space requirement increases
Solution Approach 1:
The patent segments operation setting information by storing it in different locations: frequently used setting information is stored in cache memory, while complete or alternative setting information is stored in the memory cell array. This segmentation allows the system to access常用 settings quickly from cache while maintaining access to all settings through the memory cell array, thus reducing cache memory requirements without sacrificing operational efficiency.
Solution Approach 2:
The system performs preliminary actions by pre-loading only the necessary operation setting information into cache memory based on anticipated or current operation needs. The memory cell array is prepared with complete setting information that can be loaded into cache when needed. This preliminary organization allows efficient operation execution while minimizing the amount of information that must be held in cache simultaneously.
2Quantity of substance
If the cache memory stores less operation setting information, then the cache memory size and cost are reduced, but the time to obtain and load setting information increases
Solution Approach 1:
The patent applies preliminary action by pre-organizing operation setting information in the memory cell array in a structured format that enables rapid retrieval. The information is arranged so that when needed, it can be quickly loaded into cache memory without requiring full sequential access. This preliminary organization significantly reduces the time penalty associated with smaller cache memory capacity.
Solution Approach 2:
The memory device performs self-service by automatically managing the loading of operation setting information from the memory cell array to cache memory based on operation commands received. The peripheral circuit monitors operation types and proactively loads the appropriate setting information, eliminating the need for external controllers to manually manage this data transfer, thus reducing overall system latency.
3Adaptability or versatility
If the memory device supports multiple operation types with different setting information, then the device versatility is improved, but the complexity of managing different setting information increases
Solution Approach 1:
The patent implements universality by creating a unified storage and retrieval mechanism that handles multiple operation types through a common interface. The peripheral circuit is designed to recognize different operation commands and automatically retrieve the corresponding setting information using the same basic process flow. This universal approach allows the device to support diverse operation types (read, write, erase, etc.) without requiring separate management mechanisms for each, thus reducing overall system complexity while maintaining high versatility.

AI summary
Systems, devices, and methods for managing operation setting information in memory devices are provided. In one aspect, a memory device includes a memory cell array comprising memory cells, and a peripheral circuit coupled to the memory cell array. The peripheral circuit is configured to in response to receiving a first operation command, perform a first operation corresponding to a first type of operation on the memory cell array according to first operation setting information. In response to receiving a second operation command, the peripheral circuit is configured to obtain second operation setting information from the memory cell array and perform a second operation corresponding to a second type of operation on the memory cell array according to the second operation setting information, wherein the second type of operation is different from the first type of operation.
