Latest Patents

Lambertson's latest work includes his patent for a "Compact Page-Erasable EEPROM Non-Volatile Memory." This innovative technology features a compact, electrically-erasable memory device that employs advanced programming and erasing techniques using two layers of conductive or semiconductive material. The memory cell consists of a first layer that acts as a floating gate, while a second layer is responsible for both erasing the floating gate and selecting the device for reading and programming. The device operates through the tunneling of electrons into the floating gate via hot-electron injection, providing efficient programming capabilities. Remarkably, the innovative design allows for the second layer to be common across multiple memory devices, enhancing its versatility.

In one preferred embodiment, the memory cell's erasure is achieved by tunneling electrons from the floating gate to the second layer, which may comprise a word line in a memory array. This mechanism results in a compact, page-alterable non-volatile memory array. Another embodiment utilizes bit line coupling to the floating gate, further contributing to the memory's compact design.
