Memory Interface Bit Toggling to Limit Transistor Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transistors in data paths experience degradation and end-of-life effects due to imbalanced static probability of logical states, leading to increased delay and timing uncertainty, which limits data transmission speed in conventional interfaces.
Innovation Solution
Periodically toggling bits during refresh intervals of a memory interface to reset the recovery period of transistors, thereby reducing recovery effects and improving the balance of static probability, allowing for higher data transmission speeds.

Engineering Contradiction Analysis
1Productivity
If data signals are communicated with imbalanced static probability of logical states, then data transmission can be performed, but transistor aging occurs leading to increased delay and timing uncertainty
Solution Approach 1:
The patent applies periodic action by implementing refresh intervals that periodically toggle bits in the memory interface. This periodic toggling resets the recovery period of transistors at regular intervals, preventing accumulated aging effects and delay variation while allowing continuous high-speed data transmission.
2Speed
If transistors are allowed to recover for longer periods, then transition speed improves, but timing uncertainty increases due to variation in recovery delay
Solution Approach 1:
The patent applies preliminary action by proactively resetting the transistor recovery period through periodic bit toggling during refresh intervals. This prevents the recovery delay from becoming excessive or highly variable, ensuring that transistors are always in a predictable state before the next data transmission, thereby reducing timing uncertainty.
3Productivity
If the number of transistors in the data path is increased, then data transmission capability is enhanced, but total delay increases due to cumulative aging effects
Solution Approach 1:
The patent applies periodic action by implementing refresh intervals that periodically toggle bits in the memory interface. This periodic toggling resets the recovery period of transistors at regular intervals, preventing accumulated aging effects and delay variation while allowing continuous high-speed data transmission.

AI summary
Methods, computer-readable mediums and systems for reducing transistor recovery are disclosed. Data which toggles at least one bit may be periodically communicated over a data path, where toggling of at least one bit may effectively reset the recovery period for any transistors in the data path associated with the at least one bit. Timing uncertainty associated with a given transistor may be reduced by limiting the amount of recovery experienced by the transistor. Accordingly, recovery of transistors in a data path may be limited to predetermined amount by toggling bits of the data path at a predetermined frequency, thereby reducing timing uncertainty and allowing a smaller system margin and/or higher data transmission speeds.
