Pipe Latch Circuit for Auto-Precharge Signal Generation

The patent merges the storage functions for read and write auto-precharge flags into a single pipe latch circuit. The pipe latch circuit receives both the read auto-precharge flag signal and the write auto-precharge flag signal, and stores them in the same latch structure, thereby reducing the layout area while maintaining separate control paths for reliable operation.

The pipe latch circuit is designed to serve multiple functions by storing both read and write auto-precharge flag signals in the same circuit structure. This multi-functional approach eliminates the need for separate dedicated storage circuits for each flag type, thus reducing overall layout area while preserving the reliability benefits of separate flag management.

The patent extracts the time management functions for read-to-precharge and write recovery into dedicated control signal generation circuits that operate independently. The read control signal generation circuit handles read-to-precharge timing, while the write control signal generation circuit handles write recovery timing, allowing each to be optimized separately without increasing overall system complexity.

The control signal generation is segmented into separate read and write control signal generation circuits. Each circuit is responsible for generating control signals for its specific operation type, which simplifies the design by allowing independent optimization of timing parameters and reduces the complexity of coordinating multiple timing functions.
