Capacitive-access CAM cell and its read/write circuit implementation
The implementation of a capacitive-access CAM cell along with its read/write circuitry are presented. Its advantages over a standard CAM cell are: feasibility of implementing multicell write operation, ready availability of masking of individual bits of a word for the write operation, and a higher order of cell data stability. A fully functional chip has been fabricated through MOSIS using 2 μm double-metal CMOS technology.
