Provided are nonvolatile memory transistors and devices including the nonvolatile memory transistors. A nonvolatile memory transistor includes a channel element, a gate electrode corresponding to the channel element, a gate insulation layer between the channel element and the gate electrode, an ionic species moving layer between the gate insulation layer and the gate electrode, and a source and a drain separated from each other with respect to the channel element. A motion of an ionic species at the ionic species moving layer occurs according to a voltage applied to the gate electrode. A threshold voltage changes according to the motion of the ionic species. The nonvolatile memory transistor has a multi-level characteristic.

The present invention includes innovative circuits and methods for implementing nonvolatile memories. In one embodiment, the present invention includes a method of operating a nonvolatile memory in two phases. During a first time period, a voltage is applied across nonvolatile memory element. During a second time period, a voltage is coupled through at least one capacitor to charge pump the initial voltage to a level sufficient for programming or erasing the memory element. Innovative techniques are employed to ensure that other devices in the system do not experience voltages in excess of device breakdown voltages. Additionally, embodiments of the present invention may be implemented on a simple manufacturing process.

Each memory cell (10) of a plurality of memory cells (130A-130I) of a memory has a well, source (132) and drain (133) regions, a storage layer (135), and a gate (131). The memory cells (130A-130I) are in a matrix. Same column drain regions (133) connect to the same bit line (110A-110C), same row gates (131) connect to the same word line (100A-100C), and same column source regions (132) connect to the same source line (120A-120C). The memory (10) is programmed by applying a first voltage to a word line (100A-100C) electrically connected to a memory cell (130E) of the plurality of memory cells (10), applying a second voltage different from the first voltage by at least a programming threshold to a bit line (110A-110C) electrically connected to the memory cell (130E), applying a third voltage different from the first voltage by at least the programming threshold to a source line (120A-120C) electrically connected to the memory cell (130E), and applying a substrate voltage to the plurality of memory cells (10, 130E).
