Dual voltage asymmetric memory c

Memory with asymmetric power delivery for keeper cells in the memory are provided. In some embodiments, first and second power delivery circuits use separate first and second independently regulated power supplies. The first supply may be a supply nominally used for the memory structure, while the second supply may be lower than the first supply. In some embodiments, during a write operation, the first (higher) supply is used for one of the logic elements in a keeper cell, while the second (lower) supply is used for the other keeper logic element. 提供了具有用于存储器中的保持器单元的非对称功率传送的存储器。在些实施例中，第功率传送电路和第二功率传送电路使用单独的第独立调节的电源和第二独立调节的电源。第电源可以是名义上用于存储器结构的电源，而第二电源可以比第电源要低。在些实施例中，在写入操作期间，第(较高的)电源用于保持器单元中的逻辑元件的其中之，而第二(较低的)电源用于另个保持器逻辑元件。
