Title: Innovations by Justin Penfold
Introduction
Justin Penfold is an accomplished inventor based in Suffolk, GB. He has made significant contributions to the field of electronics, particularly in memory cell technology. With a total of 3 patents to his name, Penfold continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is focused on control circuitry for memory cells. This invention describes a breakdown detection circuit designed to identify abnormally high currents that indicate a defective cell during programming. The circuit monitors the impedance level at a terminal and is connected between the device being programmed and ground. It comprises three transistors, with at least one capable of withstanding the programming voltage in case of breakdown. Other embodiments of this patent include a flag bit cell design, a memory array, and methods for reading and writing to that array.
Another notable patent by Penfold is related to electrostatic discharge protection. This circuit protects a node in an electronic device from electrostatic discharge. It features a voltage rail that provides a predetermined voltage when the device is powered. The design includes a first switching device connected between the node and ground, and a second switching device that controls the conductance of the first. This innovative approach ensures that the first switching device maintains low conductance during normal operation and allows current to flow to ground in response to an overvoltage condition.
