Burst Order Control Circuit for Timing Margin and Equal Signal Loading

The patent applies preliminary action by generating the burst signal earlier in the clock cycle and using delay elements to pre-adjust the timing. The burst signal is generated at CL-3 and delayed through multiple stages to reach the pipe latch at the appropriate time, ensuring sufficient timing margin while maintaining high data output speed.

The patent uses delay elements and repeater units as intermediary components between the burst signal generation and the pipe latch. These intermediaries buffer and condition the signals, providing adequate timing margin and preventing direct conflicts between fast toggling and circuit stability requirements.

The patent applies local quality by providing different delay paths and loading conditions for rising and falling burst signals at specific stages. The first and second rising burst signals receive different treatments from the first and second falling burst signals, allowing each to be optimized for its specific data output requirements while maintaining overall signal integrity.

The patent segments the burst signal generation into multiple independent paths: first rising burst signal path, second rising burst signal path, first falling burst signal path, and second falling burst signal path. Each path can be independently optimized with appropriate delay elements and loading conditions, preventing mutual interference and maintaining precise duty and skew characteristics.
