Abstract: We present a new spin-transfer torque magnetic random access memory (STT MRAM) bit-cell that is embedded with read-only memory (ROM) functionality. The proposed ROM-embedded STT MRAM (R-MRAM) bit-cells include one extra bit-line. ROM data is stored by selectively connecting the magnetic tunnel junction (MTJ) to one of the two bit-lines. For normal RAM-mode operations, both bit-lines are driven and sensed to switch and read the MTJ state. When reading ROM data, only one read current source is turned on and the corresponding sense amplifier is used to monitor which bit-line is connected to the bit-cell (the MTJ state can be ignored). © 2013 IEEE.
