ABSTRACT:
A memory cell (400) used to store data in an integrated circuit. The memory cell (400) is static, nonvolatile, and programmable. The layout of the memory cell is compact. A logic high output from the memory cell (400) is about VDD and a logic low output is about VSS. The memory cell (400) of the present invention includes a programmable memory element (515). In one embodiment, the programmable memory element (515) is coupled between supply voltage (510) and an output node (405). A pull-down device (525) is coupled between another supply voltage (505) and the output node (405). The memory cell (400) may be used to store she configuration information for a programmable logic device (121).
