Title: Innovations by Rahul Sud in Semiconductor Technology
Introduction
Rahul Sud is a prominent inventor based in Colorado Springs, CO (US), known for his significant contributions to semiconductor technology. With a total of 8 patents to his name, he has developed innovative solutions that enhance the efficiency and performance of semiconductor memories.
Latest Patents
One of his latest patents is a low power I/O scheme for semiconductor memories. This invention is particularly useful in wide word semiconductor memories that include both redundant and regular memory cells. The scheme conserves power by turning off conventional load transistors during write operations. Additionally, predata lines that carry data between memory cells and the main data bus also feature load transistors that are turned off during normal operations to save power. These transistors are activated during spare read or write operations to maintain the stability of unselected regular cells. Furthermore, the predata lines are held above ground potential during operations to prevent unwanted conduction of deselected column select transistors.
Another notable patent is a bootstrap driver for static RAM. This circuit operates asynchronously and utilizes a capacitor coupled between second and third nodes, with a charge pump providing charge to the second node. Address bits are applied to the gates of transistors, forming a common node linked to a low impedance transistor. An inverter is connected to the common node to apply a delayed input signal to the gates of enhancement mode transistors. This design ensures a discharge path for the third node in response to low-level memory address signals, maintaining a differential voltage across the bootstrap capacitor. The patent also includes an input protection circuit for when the bootstrap driver is used as a chip select buffer.
