  • Patent number: 8391078
    Abstract: A non-volatile DRAM cell includes a pass-gate transistor and a cell capacitor. A read operation of the non-volatile cell begins by positively charging the cell capacitor. A cell capacitor of an associated dummy non-volatile DRAM cell is fully charged. The pass-gate transistor is activated and if the pass-gate transistor is erased it does not turn on and if it is programmed, it turns on. Charge is shared on the complementary pair of pre-charged bit lines connected to the non-volatile DRAM cell and its associated Dummy non-volatile DRAM cell. A sense amplifier detects the difference in the data state stored in the pass-gate transistor. The program and erase of the non-volatile DRAM cell is accomplished Gate-induced drain-lowering (GIDL) assisted band-to-band tunneling and Fowler-Nordheim tunneling respectively. Programming or erasing a selected row of cells does not affect the data states of the cells in the unselected rows.

  • Patent number: 8320190
    Abstract: A non-volatile DRAM cell includes a pass-gate transistor and a cell capacitor. A read operation of the non-volatile cell begins by negatively charging the cell capacitor. A cell capacitor of an associated dummy non-volatile DRAM cell is fully discharged. The pass-gate transistor is activated and if the pass-gate transistor is programmed it does not turn on and if it is erased, it turns on. Charge is shared on the complementary pair of precharged bit lines connected to the non-volatile DRAM cell and its associated Dummy non-volatile DRAM cell. A sense amplifier detects the difference in the data state stored in the pass-gate transistor. The program and erase of the non-volatile DRAM cell is accomplished by charge injection from the associated bit line of the non-volatile DRAM cell.
