The memory cell comprises a storage element for storing a logical state of the memory cell powered at a reduced voltage during at least one functional operation and a write access circuit configured to connect the storage element to at least a first write bit line in the memory array in response to a write signal on the write word line for writing the logical state to the memory cell. The memory cell further comprises a read access circuit including an input node connected to the storage element and an output node connected to a read bit line of the memory array. The read access circuit is enabled and configured to read the logic state of the storage element in response to a read signal on the read word line. The reduced voltage is a voltage that is reduced relative to a peripheral operating voltage of at least one peripheral circuit associated with reading and/or writing of the memory cell. | 2011-03-24 |
