    摘要: A method and system wherein a volatile memory is partitioned to have a first percentage of address space dedicated to a first classification of data which is data that is expected to have greater than a predetermined number of times of being modified and a second percentage of address space dedicated to a second classification of data which is data that is expected to have less than the predetermined probability of being modified. Address assignment of data to be stored in the volatile memory is made on a basis of predicted change of the data. Memory addresses of the first and second percentages of address space are respectively assigned to first and second sections of nonvolatile memory. The memory addresses of the first percentage initially consume a smaller percentage of an address map of the first section than the memory addresses of the second percentage of the second section.

    摘要: A semiconductor device (30) comprises an underlying insulating layer (34), an overlying insulating layer (42) and a charge storage layer (36) between the insulating layers (34, 42). The charge storage layer (36) and the overlying insulating layer (42) form an interface, where at least a majority of charge in the charge storage layer (36) is stored. This can be accomplished by forming a charge storage layer (36) with different materials such as silicon and silicon germanium layers or n-type and p-type material layers, in one embodiment. In another embodiment, the charge storage layer (36) comprises a dopant that is graded. By storing at least a majority of the charge at the interface between the charge storage layer (36) and the overlying insulating layer (42), the leakage of charge through the underlying insulating layer is decreased allowing for a thinner underlying insulating layer (34) to be used.
