Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 18:
19. The resistive memory device of claim 16, further comprising:
a reference cell including a reference resistor and connected between a second bit line and a second source line; and
a write driver connected to the first bit line or the first source line, connected to the second bit line or the second source line, and configured to generate a write current for writing target data in the resistive memory cell,
wherein the write driver comprises a comparator configured to receive the write current, compare previous data written in the resistive memory cell with the target data by comparing a voltage of the first source line with a voltage of the second source line or by comparing a voltage of the first bit line with a voltage of the second bit line, and determine whether the target data is written in the resistive memory cell in accordance with a result of comparing the previous data with the target data, and
wherein the target data is not written in the resistive memory cell when the previous data is the same as the target data and is written in the resistive memory cell when the previous data is different from the target data.
