A non-volatile memory cell and associated method of use are disclosed. In
accordance with various embodiments, the memory cell includes a switching
device and a resistive sense element (RSE) connected in series between
first and second control lines. The first control line is supplied with a
variable voltage and the second control line is maintained at a fixed
reference voltage. A first resistive state of the RSE is programmed by
lowering the variable voltage of the first control line below the fixed
reference voltage of the second control line to flow a body-drain current
through the switching device. A different, second resistive state of the
RSE is programmed by raising the variable voltage of the first control
line above the fixed reference voltage to flow a drain-source current
through the switching device.
