Dynamically boosting read voltage for a memory device

Abstract

Systems, methods, and apparatus related to dynamically determining read voltages used in memory devices. In one approach, a memory device has a memory array including memory cells. One or more resistors are formed as part of the memory array. A memory controller increments a counter as write operations are performed on the memory cells. When the counter reaches a limit, a write operation is performed on the resistors. The write operation applies voltages to the resistors similarly as applied to the memory cells over time during normal operation. When performing a read operation, a current is applied to one or more of the resistors to determine a boost voltage. When reading the memory cells, a read voltage is adjusted based on the boost voltage. The memory cells are read using the adjusted read voltage.
