Abstract: A method for testing refresh operations of a memory array wherein subthreshold leakage current may be set to near worst-case conditions. The memory array includes a first row of memory cells having a first memory cell configured to store a first memory value, and a second row of memory cells having a second memory cell configured to store a second memory value. The method comprises storing a logic high value to the first memory cell as the first memory value, followed by storing a logic low value to the second memory cell as the second memory value. The method further comprises repeatedly driving a write bit line coupled to both the first and second memory cells at a logic low level for a period of a time equal to a refresh interval corresponding to the first memory cell. Additionally, the method includes subsequently reading the first memory value from the first memory cell.
