Abstract:
Methods, systems, and devices for reading a multi-level memory cell are described. The memory cell may be configured to store three or more logic states. The memory device may apply a first read voltage to a memory cell to determine a logic state stored by the memory cell. The memory device may determine whether a first snapback event occurred and apply a second read voltage based on determining that the first snapback event failed to occur based on applying the first read voltage. The memory device may determine whether a second snapback event occurred and determine the logic state based on whether the first snapback event or the second snapback event occurred.
