    Abstract: Techniques are disclosed for forming resistive random-access memory (RRAM) including a tunnel source access transistor, such as a tunnel source MOSFET. The use of a tunnel source access transistor includes integrating a tunnel diode on the bitcell transistor's source terminal using epitaxial growth. Accordingly, such RRAM bitcells are referred to herein as having a 1T(D)-1R configuration. As can be understood based on this disclosure, the tunnel diode's resistance is asymmetric with respect to RRAM write voltage. Thus, the tunnel diode optimizes array operations for the 1T(D)-1R bitcells described herein, enabling both control of current compliance in the SET direction and maximization of current in the RESET direction from the same RRAM bitcell. The 1T(D)-1R architecture is compatible with a multitude of RRAM device structures and transistor types, such as NMOS and PMOS configurations. Further, the tunnel diode can be integrated in a MOSFET access transistor without increasing cell layout area.

    Abstract: Embodiments include apparatuses, methods, and systems for a circuit to shift a voltage level. The circuit may include a first inverter that includes a first transistor coupled to pass a low voltage signal and a second inverter coupled to receive the low voltage signal. The circuit may further include a second transistor coupled to receive the low voltage signal from the second inverter to serve as a feedback device and produce a high voltage signal. In embodiments, the first transistor conducts asymmetrically to prevent crossover of the high voltage signal into the low voltage domain. A low voltage memory array is also described. In embodiments, the circuit to shift a voltage level may assist communication between a logic component including the low voltage memory array of a low voltage domain and a logic component of a high voltage domain. Additional embodiments may also be described.
