Title: Innovations of James W Grace
Introduction
James W Grace is a notable inventor based in Los Altos Hills, California. He holds a total of 14 patents, showcasing his significant contributions to the field of integrated circuits and memory technology. His work has paved the way for advancements in chip identification and memory testing.
Latest Patents
One of his latest patents is for a Permanent Chip ID using FeRAM. This innovation involves an integrated circuit (IC) chip that contains a small non-volatile 'ID' memory, such as an FeRAM array. This memory stores essential information related to the manufacturing, testing, and performance of the IC chip. The stored data can include a serial number, wafer ID, batch ID, date code, chip history, test data, and performance information. By storing this information directly on the chip, it eliminates the challenges of matching data with the IC chip and provides a flexible permanent record for manufacturers. This ID memory allows for tracking and identification of ICs in a way that was previously impractical. Additionally, a self-test feature can compare prior test results stored in the ID memory with current results to detect defects or select operating parameters of the integrated circuit.
Another significant patent is for Accelerated Fatigue Testing. In this innovation, a memory such as FeRAM implements accelerated fatigue operations that can rapidly change the storage state of numerous memory cells simultaneously. The design includes multiple segments with isolated plate lines, allowing for efficient testing. This method ensures that every FeRAM cell is equally fatigued through a series of systematic operations.
