Output Latch Circuitry for Faster Memory Signal Transitions

The patent applies preliminary action by pre-charging the output nodes before the actual data transition occurs. The output nodes are prepared with appropriate voltage levels in advance, so when the data transition happens, the output can switch states immediately without waiting for the full propagation delay through the cross-coupled NAND gates. This reduces the asymmetric rising and falling transition delays while maintaining reliable data storage functionality.

The patent segments the output buffer into multiple independent stages that can operate in parallel rather than sequentially. By dividing the output buffering function across multiple stages with separate control signals, the system eliminates the sequential propagation delay through cross-coupled gates. Each stage can transition independently, significantly reducing memory access time while maintaining data storage reliability.

The patent introduces intermediary control signals and additional buffering stages that mediate between the simple latch core and the external memory system. These intermediary elements include pre-charge control signals, enable signals, and multi-stage output buffers that accelerate data transfer. While these additions increase circuit complexity, they dramatically improve processor-memory interaction speed by eliminating the bottlenecks present in conventional latch designs.
