Memory Device Internal Dummy Data Generation to Reduce Transmission Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of filling dummy data in memory devices is time-consuming and inefficient, as it involves transmitting dummy data from the memory controller, which is not of interest to the user and consumes valuable transmission time.
Innovation Solution
The memory device generates dummy data internally based on its own characteristics and algorithms, rather than receiving it from the memory controller, thereby reducing transmission time and improving throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dummy data is transmitted from the memory controller to the memory device, then the memory device can fill dummy data in the memory cell array, but the transmission process consumes valuable time and reduces system throughput
Solution Approach 1:
The memory device generates dummy data autonomously using its own internal resources (pseudo-random number generator or lookup table) rather than receiving it from the memory controller. This self-service approach eliminates the transmission step entirely, resolving the contradiction by maintaining dummy data filling functionality while removing the time-consuming transmission process
Solution Approach 2:
The dummy data generation function is extracted from the memory controller and relocated to the memory device itself. By taking out the generation responsibility from the controller and embedding it in the memory device, the patent eliminates the need for data transmission while ensuring the memory device has the capability to fill dummy data independently
2Ease of operation
If dummy data is transmitted from the memory controller, then the memory device receives the data, but the transmission of unnecessary data reduces overall system efficiency
Solution Approach 1:
The memory device performs self-service by generating its own dummy data internally, eliminating the need for the memory controller to prepare and transmit dummy data. This maintains the ease of operation for dummy data filling while significantly improving system throughput by removing unnecessary data transmission
Solution Approach 2:
Instead of the conventional approach where the controller generates and sends dummy data to the memory device, the patent inverts the workflow: the memory device generates dummy data itself and then fills it into the memory cell array. This inversion eliminates the transmission step and improves overall system efficiency

AI summary
According to one aspect of the present disclosure, a memory device is provided. The memory device includes a memory cell array and a peripheral circuit coupled to the memory cell array. The peripheral circuit is configured to receive a first instruction, in response to the first instruction, generate a dummy data and write the dummy data in the memory cell array, receive a second instruction indicating to perform a read operation in the memory cell array, and send a returned data based on the read operation. In response to a read data of the read operation comprising the dummy data, the returned data is set feature information indicating that the returned data comprises the dummy data.
