Abstract
An electronic data-storage apparatus having ROM embedded in an STT-MRAM. The apparatus comprises at least two bit lines, a plurality of bit cells, each including, connected to a source line (SL), a series connection (in any order) of a selection element (e.g., transistor gated by word line WL), a resistive storage element (e.g., MTJ), and a permanent connection to one of the bit lines (e.g., BL, BL). The apparatus may also include a ROM sense amplifier which is configured to precharge two output nodes connected to respective ones of the bit lines, so that the jumper in a selected memory cell pulls one of the output nodes to a first reference potential (e.g., GND) and the ROM sense amplifier pulls the other of the output nodes to a second reference potential (e.g., Vdd).
