Engineering Contradiction Analysis
1Measurement precision
If the quantity of clock cycles is determined using existing quantization methods, then the calculation is simple, but timing errors occur and performance decreases
Solution Approach 1:
The patent modifies the quantization parameters by introducing a correction factor that adjusts the relationship between clock cycle duration and access duration. Instead of using a fixed quantization method, the system dynamically adjusts the clock cycle quantity calculation by applying a correction factor derived from the ratio of maximum access duration to quantized maximum access duration, thereby resolving the timing errors while maintaining computational efficiency
2Ease of operation
If quantization is applied to clock cycle duration, then the calculation process is simplified, but errors in determining maximum duration are introduced
Solution Approach 1:
The patent implements a feedback mechanism where the correction factor is calculated based on the discrepancy between the actual maximum access duration and the quantized maximum access duration. This feedback loop allows the system to continuously refine the clock cycle quantity calculation, ensuring that timing accuracy is maintained even as quantization simplifies the overall calculation process

AI summary
Methods, systems, and devices for maximum memory clock estimation procedures are described. For instance, a device, such as a host device, may truncate a value of a first parameter associated with a first duration for a clock coupled with a memory array to perform a clock cycle and may estimate a value of a second parameter that is inversely proportional to the truncated value of the first parameter. The device may determine a quantity of clock cycles associated with a maximum duration for accessing one or more memory cells of the memory array based on adjusting the second parameter. The device may access the one or more memory cells of the memory array based on the determined quantity of clock cycles associated with the maximum duration.
