Abstract
- International audience; Multi-Level Cell (MLC) technology can greatly reduce Resistive RAM (RRAM) die sizes to achieve a breakthrough in cost structure. In this paper, a novel design scheme is proposed to realize reliable and uniform MLC RRAM operation without the need of any read verification. MLC is implemented based on a strict control of the cell programming currents of 1T-1R HfO 2 -based RRAM cells. Specifically, a self-adaptive write termination circuit is proposed to control the RRAM RESET current. Eight different resistance states are obtained by varying the compliance current which is defined as the minimal current allowed by the termination circuit in the RESET direction.
