Classification: CPC G | IPC G

Claim 0:
1. A resistive memory device, comprising:
a plurality of word lines;
a plurality of first memory cells coupled to the word lines;
a plurality of second memory cells coupled to the word lines;
a plurality of bit lines coupled to the first memory cells and the second memory cells;
a plurality of source lines coupled to the first memory cells and the second memory cells;
a driver configured to provide a forming voltage to the first memory cells and the second memory cells through the bit lines and the source lines in a forming process performed to the first memory cells and the second memory cells,
wherein a first connection length along the bit lines and the source lines between the first memory cells and the driver is longer than a second connection length along the bit lines and the source lines between the second memory cells and the driver, and the forming process is performed to the first memory cells before the forming process is performed to the second memory cells,
wherein during the forming process, a first value of the forming voltage provided to the first memory cells is less than a second value of the forming voltage provided to the second memory cells; and
a plurality of third memory cells coupled to the word lines,
wherein the second connection length along the bit lines and the source lines is longer than a third connection length along the bit lines and the source lines between the third memory cells and the driver, and the forming process is performed to the second memory cells before the forming process is performed to the third memory cells,
wherein during the forming process, the second value of the forming voltage provided to the second memory cells is less than a third value of the forming voltage provided to the third memory cells.
