摘要:
Apparatus and method for providing overcurrent protection to a resistive random access memory (RRAM) cell during an RRAM formation process used to prepare the cell for normal read and write operations. In accordance with various embodiments, the RRAM cell is connected between a first control line and a second control line, and an active protection device (APD) is connected between the second control line and an electrical ground terminal. A formation current is applied through the RRAM cell, and an activation voltage is concurrently applied to the APD to maintain a maximum magnitude of the formation current below a predetermined threshold level
