Abstract:
Techniques for reading a Multi-Bit Cell (MBC) can include sensing a state parameter value, such as source line voltage, and applying a successive one of N programming parameter values, such as successive programming currents, between instances of sensing the state parameter values. The N successive programming parameter values can be selected to switch the state of a corresponding one of N cell elements of the MBC. Successive ones of the sensed state parameter values can be compared to determine N state change results, which can be used to determine the read state of the MBC.

Claim (Index 12):
A memory device comprising:\n a Multi-Bit Cell (MBC) coupled between a bit line and a source line, wherein the MBC includes a first MTJ element, a second MTJ element and a selector coupled in series, wherein the first and second MTJ elements have different low-resistance levels and different high-resistance levels, and wherein the first and second MTJ elements have opposite pinned magnetization polarization orientations; one or more memory circuits configured to;\n receive a read command for a selected plurality of MBCs; \n sense for each selected MBC a first sense voltage of the MBC; \n program the selected plurality of MBCs using a first program voltage after sensing the first sense voltage, wherein the first MTJ element will be in a first known state after programming; \n sense for each selected MBC a second sense voltage of the MBC after programming the MBC using the first program voltage; \n compare for each selected MBC the second sense voltage to the first sense voltage, after sensing the second sense voltage, to determine a first resistance change state; \n program the selected plurality of MBCs using a second program voltage after sensing the second sense voltage, wherein the state of the second MTJ element will be in a second known state after programming; \n sense for each selected MBC a third sense voltage of the MBC after programming the MBC using the second program voltage; \n compare for each selected MBC the third sense voltage to the second sense voltage, after sensing the third sense voltage, to determine a second resistance changed state; and \n determine a read state of the MBC based on the first resistance change state and the second resistance change state; and \n output the read state of the selected plurality of MBCs in response to the received read command.
