Latest Patents
Hernandez's latest patents include a method of screening memory cells at room temperature and a method of screening hot temperature erase rejects at room temperature. The first patent outlines a process for screening hot temperature programmability rejects during wafer sort at room temperature. This method involves subjecting all cells in the memory device to a sequence of programming pulses at a voltage lower than the standard programming voltage. Cells that successfully verify as programmed are passed, while those that do not are subjected to a second sequence of programming pulses for further testing.
The second patent focuses on screening hot temperature erase rejects. In this method, selected cells undergo a sequence of erasure pulses at a high voltage until they are verified as erased or a maximum number of pulses is reached. This process ensures that defective memory cells are identified and repaired, enhancing the overall quality of the memory devices.
