Application: Programming of a selected non-volatile memory cell (Patent ID: US20230368011A1)
The patent filed by Microchip Technology Inc. describes a method for programming non-volatile memory cells using a series of program-verify cycles with increasing programming voltage durations applied to different terminals of the memory cell. The method involves verifying the current through the memory cell during read or verify operations and adjusting the programming duration based on the measured current to achieve specific threshold values.
The claims outline various aspects of the method, including applying different voltages to control gate and erase gate terminals, erasing the memory cell if current thresholds are not met, and performing multiple programming processes until specific current threshold values are achieved. The method is applicable to split-gate flash memory cells and can be used in vector-by-matrix multiplication arrays in analog neural networks. Additionally, the patent covers programming logical multi-bit cells with physical non-volatile memory cells of uniform or non-uniform width to achieve specific current targets. Overall, the patent details a comprehensive method for efficient and precise programming of non-volatile memory cells.
