    摘要: A memory device includes a plurality of memory cells arranged in series in the semiconductor body, such as a NAND string, having a plurality of word lines. A selected memory cell is programmed by hot carrier injection using a boosted channel potential to establish the heating field. Boosted channel hot carrier injection can be based on blocking flow of carriers between a first side of a selected cell and a second side of the selected cell in the NAND string, boosting by capacitive coupling the first semiconductor body region to a boosted voltage level, biasing the second semiconductor body region to a reference voltage level, applying a program potential greater than a hot carrier injection barrier level to the selected cell and enabling flow of carriers from the second semiconductor body region to the selected cell to cause generation of hot carriers.

    摘要: A multi-Level Cell (MLC) can be used to store, for example, 4 bits per cell by storing two bits on each of two sides. Each side can store, e.g., four different current level states that can be determined by the number of holes injected into, e.g., nitride layer, during programming. As more holes are injected the current decreases for a given voltage. The current can be low, therefore, it can be advantageous in one embodiment to use a current amplifier. The current amplifier can be a BJT, MOS or other type of device.

    摘要: A method for programming a first memory cell in a memory array. In a specific embodiment, each memory cell has a drain, a source, a channel, and a control gate overlying a charge storage material and the channel. The source of the first memory cell is coupled to the drain of a second memory cell. A voltage is applied to the drain of the first memory cell, and the source of the second memory cell is grounded. The method includes floating the drain of the second memory cell and the source of the first memory cell and turning on the channels of the first and second memory cells, effectively forming an extended channel region. Hot carriers are injected to the charge storage material of the first cell to program the first memory cell. The extended channel lowers electrical fields and reduces punch through leakage in unselected memory cells.
