Command Path Clock Circuit for Back-to-Back Command Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic memory systems consume significant power due to continuous clock signal transitions during memory operations, particularly in battery-powered devices, where reducing power consumption is desirable.
Innovation Solution
Implementing a command path circuit that detects back-to-back commands and switches to an inactive clock signal for portions of the command cycle, reducing power consumption by eliminating unnecessary active clock signal transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active clock signals are provided continuously to the command path circuit, then the circuit operates reliably and commands are processed without delay, but power consumption increases
Solution Approach 1:
The patent applies periodic action by providing active clock signals only during specific periods when commands are present and require processing, rather than continuously. The clock signal is activated during command cycles and deactivated during idle periods, creating a periodic on/off pattern that reduces power consumption while maintaining operational reliability when needed.
Solution Approach 2:
The patent implements dynamics by making the clock signal state variable - it can switch between active and inactive states based on command presence. The command path circuit dynamically adjusts its operational state, transitioning from idle to active mode when commands arrive, ensuring reliable operation during processing while minimizing power consumption during idle periods.
2Use of energy by moving object
If inactive clock signals are provided during command cycles, then power consumption is reduced, but the circuit may not process commands efficiently
Solution Approach 1:
The patent uses periodic action to activate the clock signal specifically during command cycles when processing is required. The clock remains inactive during idle periods but transitions to active state periodically when commands are detected, ensuring that productivity is maintained during necessary operations while power consumption is reduced during idle time.
Solution Approach 2:
The command path circuit implements self-service by automatically detecting the presence of commands and activating the clock signal only when needed. The circuit monitors its own input conditions and autonomously switches between idle and active states, ensuring that productivity requirements are met without external control while minimizing unnecessary power consumption.

AI summary
Apparatuses and methods for providing active and inactive clock signals to a command path circuit are described. An example method includes providing an active clock signal to a command path for a first portion of a command cycle for a command of back-to-back commands. The command path decodes the command and provides an output command signal responsive to the clock signal. The method further includes providing an inactive clock signal to the command path for a second portion of the command cycle for the command of the back-to-back commands.
