Semiconductor Buffer Control Signal Generation Circuit

The patent applies preliminary action by generating a reset signal in advance based on the write command signal before the data strobe signals become unstable. This reset signal is used to initialize the input control signals at the appropriate timing, ensuring they are stable before data operations begin. The buffer control signal generation circuit generates the buffer control signal in synchronization with the write command signal, which then controls the data strobe signal buffer to produce stable internal data strobe signals.

The patent introduces intermediary elements including the buffer control signal generation circuit, data strobe signal buffer, and reset signal generator. These intermediaries process and condition the signals between the write command signal and the input control signals, filtering out instabilities from the data strobe signals and producing clean, stable input control signals synchronized with the write command timing.

The patent merges multiple functions into integrated circuits: the buffer control signal generation circuit combines write command signal processing with buffer control signal generation; the data strobe signal buffer combines signal buffering with stabilization; and the reset signal generator integrates timing detection with reset signal generation. This consolidation achieves signal stability while minimizing the increase in device complexity through functional integration.

The control circuits designed in the patent serve multiple functions: the buffer control signal generation circuit not only generates buffer control signals but also synchronizes with the write command signal; the data strobe signal buffer both buffers and stabilizes signals; the reset signal generator both detects timing and generates initialization signals. This multi-functionality reduces the need for separate dedicated circuits, thereby limiting complexity growth.
