Latest Patents
One of his latest patents is focused on flash memory with buried bit lines. This patent describes a memory cell and a method of forming the same. The memory cell is constructed on a substrate and includes a floating gate that is partially formed within the substrate. A bit line region is also formed within the substrate, positioned close to the floating gate. This configuration allows for memory cells to be located closer together, thereby increasing the density of memory cells in a memory array. Another significant patent involves a method of programming a flash memory cell. This method includes applying a first programming voltage to one of several wordlines corresponding to the cell to be programmed. The first programming voltage is designed to match the desired threshold voltage. Additionally, a second programming voltage is applied to one of the bitlines, which gradually increases from a low level to a high level. The programming voltages are removed when the corresponding bitline current begins to decrease.
