Abstract:
A method of writing a memory cell includes, during a write cycle, causing a voltage level at a power terminal of the memory cell to change from a supply voltage level toward a first voltage level. The voltage level at the power terminal of the memory cell is maintained at the first voltage level for a first predetermined duration. The voltage level at the power terminal of the memory cell is maintained at a second voltage level for a second predetermined duration, where the second voltage level is between the first voltage level and the supply voltage level. During the write cycle, the voltage level at the power terminal of the memory cell is caused to change from the first voltage level toward the supply voltage level.
