The interface layer has a physical memory attribute module and a physical memory protection module. The interface layer manages memory attributes and memory security. The overlay application layer is coupled to the interface layer and executes an exception handler process to check if an overlay exception has occurred. The memory relocatable layer, coupled to the interface layer and the overlay application layer, having a plurality of resident service program within a first memory space, an overlay physical region within a second memory space, and a plurality of overlay virtual regions having application processes within a third memory space. The application processes of one of the overlay virtual regions is determined to be executed by the PMA module and is copied from the overlay virtual region to the overlay physical region by a processor.

Abstract: A manufacturing method for a nonvolatile charge-trapping memory apparatus is provided. During the manufacturing process of the nonvolatile memory apparatus, a blocking layer of a storage device is effectively protected. Consequently, the blocking layer is not contaminated or thinned. Moreover, since the well regions of the logic device area and the memory device area are not simultaneously fabricated, it is feasible to fabricate small-sized nonvolatile memory cell in the memory device area and precisely control the threshold voltage of the charge trapping transistor.

A gate structure of the storage transistor includes a first tunneling layer, a second tunneling layer, a trapping layer, a blocking layer and a gate layer. The first tunneling layer is contacted with a surface of the well region. The second tunneling layer covers the first tunneling layer. The trapping layer covers the second tunneling layer. The blocking layer covers the trapping layer. The gate layer covers the blocking layer. The second tunneling layer has gradient nitrogen distribution. A first nitrogen concentration of a first region of the second tunneling layer close to the first tunneling layer is lower than a second nitrogen concentration of a second region of the second tunneling layer close to the trapping layer.

Abstract: A present invention relates to a method of erasing a P-channel non-volatile memory is provided. This P-channel non-volatile memory includes a select transistor and a memory cell connected in series and disposed on a substrate. In the method of erasing the P-channel non-volatile memory, holes are injected into a charge storage structure by substrate hole injection effect. Hence, the applied operational voltage is low, so the power consumption is lowered, and the efficiency of erasing is enhanced. As a result, an operational speed of the memory is accelerated, and the reliability of the memory is improved.
