Abstract:
A semiconductor device that includes a memory cell having a junction field effect transistor (JFET) used to form a content addressable memory (CAM) cell is disclosed. The JFET may include a data storage region disposed between a first and second insulating region. The data storage region provides a first threshold voltage to the JFET when storing a first data value and provides a second threshold voltage to the JFET when storing a second data value. The memory cell is a dynamic random access memory (DRAM) cell and can be used to form a CAM cell. The CAM cell may be a ternary CAM cell formed with as few as two JFETs.
