Title: **David J. Toops: Innovator in Semiconductor Technology**

Introduction

David J. Toops, an accomplished inventor based in Lucas, Texas, has made significant contributions to the field of semiconductor technology. With a remarkable portfolio of 15 patents, his innovative designs and devices continue to push the boundaries of functionality and efficiency in modern electronics.

Latest Patents

Among his latest contributions to the industry, two notable patents stand out. The first is the **High Speed Differential ROM**, which is a semiconductor device featuring a Read-Only Memory (ROM), a differential sense amplifier, and a multiplexer logic circuit. This device incorporates memory cells organized in rows along word lines and columns along bit lines, along with a reference column equipped with reference transistors. The multiplexer logic circuit is designed to connect a selected bit line to the first differential amplifier input, while the reference bit line connects to the second differential amplifier input. This innovative setup allows precise control of the reference current, enhancing performance between programmed and unprogrammed memory cells.

The second patent is the **Resistor-Capacitor (RC) Delay Circuit with a Precharge Mode**, which includes transistors for precharging and discharging, driven by input signals. This circuit is ingeniously designed to utilize a resistor with a negative temperature coefficient to create a node in conjunction with a capacitive device and an inverter. The precharge transistor is turned on for a certain polarity of input signal, enabling current to flow and charge the capacitive device. In contrast, a different polarity switches the state of the transistors, enabling discharge through the resistor and affecting the inverter’s output. This design not only optimizes the charging process but also enhances the overall efficiency of signal processing in semiconductor applications.
