摘要:
A data retention monitor for a memory cell including a voltage source and a voltage comparator. The voltage source is adapted to provide a selectable voltage to the memory cell. The selectable voltage includes a read voltage and a test voltage, with the test voltage being greater than the read voltage. The voltage comparator is adapted to compare a voltage of the memory cell with a reference voltage after the provision of the selectable voltage to the memory cell. The memory cell retains data when the memory cell voltage generated at least in part by the test voltage is substantially equal to the reference voltage.
