Abstract:
Providing for a high performance and efficiency NAND architecture is described herein. By way of example, a NAND array is disclosed comprising memory cells having a 1 transistor-1 two-terminal memory device (IT-1D) arrangement. Memory cells of the NAND array can be arranged electrically in serial with respect to each other, from source to drain. Moreover, respective memory cells comprise a transistor component connected in parallel to a two-terminal memory device. In some embodiments, a resistance of the activated transistor component is selected to be substantially less than that of the two-terminal memory device, and the resistance of the deactivated transistor component is selected to be substantially higher than the two-terminal memory device. Accordingly, by activating or deactivating the transistor component, a signal applied to the memory cell can be shorted past the two-terminal memory device, or directed through the two-terminal memory device, respectively.
