Semiconductor Bank Address Storage for Read Write Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor devices require multiple clock cycles and repeated transmission of bank addresses for read and write operations, leading to inefficiencies in data transmission and increased power consumption, as well as limitations in data retention and processing speed.
Innovation Solution
A semiconductor device configuration that stores a bank address applied to an active signal from command signals, allowing for reduced clock cycles in operations by using a decoder, register, and bank to perform read/write operations based on a single bank address, thereby minimizing address pins and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional semiconductor devices use multiple clock cycles and repeated transmission of bank addresses for read and write operations, then data transmission accuracy is maintained, but data transmission efficiency decreases and power consumption increases
Solution Approach 1:
The patent applies preliminary action by storing the bank address in a register during the active signal phase, so that the bank address is already available when the read or write command is executed. This eliminates the need to retransmit the bank address in subsequent clock cycles, thereby reducing the total number of clock cycles required and improving data transmission efficiency.
Solution Approach 2:
The register is designed to serve multiple functions: it stores the bank address during the active signal phase and retains it for subsequent read/write operations. This multi-functionality allows the same stored bank address to be used across multiple operations, reducing redundant transmissions and lowering power consumption.
2Reliability
If conventional semiconductor devices repeatedly transmit bank addresses for each operation, then operation reliability is maintained, but power consumption increases
Solution Approach 1:
The bank address is preliminarily stored in the register during the active signal phase, ensuring it is reliably captured and retained for subsequent operations. This preliminary storage maintains operation reliability while eliminating the need for repeated transmissions that would increase power consumption.
Solution Approach 2:
The register automatically retains the bank address without requiring external retransmission or refresh operations. This self-service mechanism ensures the bank address remains reliably available for multiple operations without additional power expenditure for repeated transmissions.
3Speed
If conventional semiconductor devices use multiple clock cycles for command execution, then data accuracy is ensured, but processing speed decreases
Solution Approach 1:
The bank address is preliminarily stored in the register during the active signal phase, so that when the read or write command is issued, the bank address is already available. This eliminates the need for additional clock cycles to retransmit the bank address, thereby reducing command execution time and improving processing speed.
4Productivity
If conventional semiconductor devices transmit bank addresses in synchronization with clock signals, then data communication accuracy is maintained, but data transmission efficiency decreases
Solution Approach 1:
The bank address is preliminarily stored in the register during the active signal phase in synchronization with the clock signal, ensuring accurate capture. The stored address is then retained for subsequent operations without requiring retransmission, thereby maintaining data communication accuracy while improving data transmission efficiency.
