发明名称 Configuring resistive random access memory (RRAM) array for write operations
摘要 A system includes a resistive random access memory cell and a driver circuit. The resistive random access memory cell includes a resistive element and a switching element, and has a first terminal connected to a bit line and a second terminal connected to a word line. The driver circuit is configured to apply, in response to selection of the resistive random access memory cell using the word line, a first voltage of a first polarity to the bit line to program the resistive random access memory cell to a first state by causing current to flow through the resistive element in a first direction, and a second voltage of a second polarity to the bit line to program the resistive random access memory cell to a second state by causing current to flow through the resistive element in a second direction.
