Nonvolatile Spintronic Memory Array Performance Benchmarking Based on Three-Terminal Memory Cell
For the conventional spin-transfer torque random access memory, tradeoffs exist between read margin and write energy because both read and write currents pass through the same magnetic tunnel junction. To improve the read/write performance and reduce the read disturb rate, three-terminal memory cell...

For the conventional spin-transfer torque random access memory, tradeoffs exist between read margin and write energy because both read and write currents pass through the same magnetic tunnel junction. To improve the read/write performance and reduce the read disturb rate, three-terminal memory cell structures are investigated and the tradeoffs among read and write performance metrics are explored. A uniform memory array-level benchmarking is performed to compare various spintronic write mechanisms, including spin diffusion, spin Hall effect, domain wall motion, and magnetoelectric (ME) effect. Results show that three-terminal memory cells have the advantage of a small write energy dissipation, and up to two orders of magnitude reduction in the energy-delay product is projected for the domain wall and ME-based memory cells. |
