Write error counter for media management in a memory device

Abstract

Systems, methods, and apparatus related to memory devices. In one approach, a memory device includes a sense amplifier, a counter, and memory having memory cells. Access lines are used to select the memory cells for performing write operations. The memory device includes a controller to control the applying of a voltage to the memory cell. The voltage is applied during a write operation using the access lines. The sense amplifier is used to determine whether the memory cell reaches a threshold state or snaps. In response to determining that the memory cell does not snap, a write error count is incremented using the counter. The controller reads the counter to determine the write error count, and based on the write error count, the controller performs one or more media management or memory device control actions.
