Abstract:
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.
