Voltage Generator with Level Compensator for Peripheral Circuit Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semiconductor memory devices face instability in external voltage levels due to high power consumption, leading to voltage drops in peripheral circuits, especially during read and write operations, and this instability affects device performance and power efficiency.
Innovation Solution
A voltage generator with a voltage level compensator and supplier is introduced, where the voltage level compensator temporarily increases the peripheral circuit voltage in response to column path commands and the supplier maintains the voltage at a reference level, using a P-channel metal-oxide semiconductor transistor and control unit to manage power supply based on operational modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the voltage level of peripheral circuit is restricted to minimize driving current, then power consumption is reduced, but external voltage level becomes unstable during high current operations
Solution Approach 1:
The voltage generator dynamically adjusts the peripheral circuit voltage level based on operational mode. During read/write operations, it increases voltage to ensure stability, while during idle periods, it maintains lower voltage to minimize power consumption. This dynamic adjustment resolves the contradiction between power savings and voltage stability.
Solution Approach 2:
The system changes the voltage parameter of the peripheral circuit based on operational requirements. By switching between different voltage levels (higher during active operations, lower during idle), the system achieves both low power consumption and stable voltage during critical operations.
2Ease of manufacture
If voltage generator is disposed in specifically designated portion, then device layout is optimized, but devices located away from voltage generator receive lowered voltage level
Solution Approach 1:
The voltage generator is configured to operate in multiple voltage levels, adding a voltage dimension to the solution. Instead of moving the voltage generator physically closer to all devices, the system provides multiple voltage levels from the same location, with higher voltage levels compensating for distance-related voltage drops to distant devices.
3Loss of energy
If peripheral circuit voltage is maintained at reference level, then power consumption is minimized, but voltage drops occur during read and write operations
Solution Approach 1:
The voltage generator applies periodic voltage boosting during read and write operations. The peripheral circuit voltage is maintained at reference level during idle periods, and temporarily increased during active operations, creating a periodic pattern that balances power consumption and operational reliability.
