Abstract
The present invention relates to a nonvolatile memory such as, for example a ROM or an EPROM, in which the information density of the memory is increased relative to a conventional nonvolatile memory that includes two logic state devices. Specifically, the nonvolatile memory of the present invention includes a SiN/TaN/SiN thin film resistor embedded within a material having a thermal conductivity of about 1 W/m-K or less; and a non-linear Si-containing device coupled to the resistor. Read and write circuits and operations are also provided in the present application.
