Patent attributes
Methods of operating memory might include storing information indicative of a data value of a digit of data stored in a particular memory cell of the memory prior to programming a subsequent digit of data to the particular memory cell, programming the subsequent digit of data to the particular memory cell, monitoring a voltage level of a supply voltage to the memory while programming the subsequent digit of data, and, if the voltage level of the supply voltage falls below a threshold while programming the subsequent digit of data and the information indicative of the data value of the digit of data has a particular logic level, causing a change in threshold voltage of one memory cell of a pair of gate-connected non-volatile memory cells, and inhibiting the other memory cell of the pair of gate-connected non-volatile memory cells from a change in threshold voltage.
