Solution Overview
Problem
Semiconductor memory devices experience high power consumption during write and read operations due to a fixed number of bits being processed, leading to increased energy usage in memory systems and electronic devices.
Innovation Solution
A semiconductor memory device that processes mode set codes and data bit number information to dynamically adjust the number of bits processed during operations, using a control device to generate data signals for write and read commands, and a memory cell array to input or output data based on selected memory cells, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a fixed number of bits is processed during write and read operations, then data consistency is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic bit processing by enabling the semiconductor memory device to flexibly adjust the number of bits processed during write and read operations based on external commands. The control device receives a command indicating a data bit number and processes only that specific number of bits, allowing the system to adapt between processing 1 bit or multiple bits per operation. This dynamic approach resolves the contradiction by making the bit processing quantity variable rather than fixed, thereby reducing unnecessary power consumption while maintaining operational flexibility.
Solution Approach 2:
The patent changes the parameter of data bit number from a fixed value to a variable parameter that can be dynamically adjusted through external commands. The control device processes a command containing data bit number information and accordingly adjusts the number of bits input to or output from memory cells. This parameter change enables the system to optimize power consumption by processing only the required number of bits, directly addressing the technical contradiction between energy efficiency and adaptability.
2Productivity
If the number of bits processed is increased, then data throughput improves, but power consumption increases
Solution Approach 1:
The patent applies partial action by allowing the system to process only the necessary number of bits required for each operation, rather than always processing the maximum number of bits. The control device receives commands specifying data bit numbers and processes exactly that many bits, enabling partial processing when full bandwidth is not needed. This resolves the contradiction by matching the processing quantity to actual requirements, improving energy efficiency while maintaining the capability for high throughput when necessary.
