Zusammenfassung:The present invention relates to the field of integrated circuit memory technology. More specifically, the present invention provides a static nonvolatile memory cell for storing data. A memory cell () used to store data in an integrated circuit. The memory cell () is static, nonvolatile, and programmable. The layout of the memory cell is compact. A logic high output from the memory cell () is about VDD and a logic low output is about VSS. The memory cell () of the present invention includes a programmable memory element (). In one embodiment, the programmable memory element () is coupled between supply voltage () and an output node (). A pull-down device () is coupled between another supply voltage () and the output node (). The memory cell () may be used to store the configuration information for a programmable logic device ().
