Latest Patents

Fujino's latest patents include advancements in static semiconductor memory devices that feature improved characteristics. One of his innovations involves a delay circuit that delays an internal write control signal to a global write driver. This global write driver is activated in response to the delayed write control signal, allowing it to drive a global write data bus based on internal write data from an input buffer. Additionally, a block write driver is enabled by an internal write control signal and a block selection signal, which drives a local write data bus according to data on the global write data bus. The design also includes a write gate that connects a bit line to the local write data bus based on a column selection signal. The delay circuit ensures that the output of the block write driver remains low for a specified period, reducing the precharge potential of the bit line and consequently lowering the potential amplitude during data writing. This innovation results in a high-speed SRAM with an enlarged write recovery time margin, enhancing both operating characteristics and reliability.
