In accordance with an embodiment of the present invention, a static random access memory (SRAM) cell comprises a first pull-down transistor, a first pull-up transistor, a first pass-gate transistor, a second pull-down transistor, a second pull-up transistor, a second pass-gate transistor, a first linear intra-cell connection, and a second linear intra-cell connection. Active areas of the transistors are disposed in a substrate, and longitudinal axes of the active areas of the transistors are all parallel. The first linear intra-cell connection electrically couples the active area of the first pull-down transistor, the active area of the first pull-up transistor, and the active area of the first pass-gate transistor to a gate electrode of the second pull-down transistor and a gate electrode of the second pull-up transistor. The second linear intra-cell connection electrically couples the active area of the second pull-down transistor, the active area of the second pull-up transistor, and the active area of the second pass-gate transistor to a gate electrode of the first pull-down transistor and a gate electrode of the first pull-up transistor.

A memory device including a programmable resistive memory material is described along with methods for manufacturing the memory device. A memory device disclosed herein includes top and bottom electrodes and a multilayer stack disposed between the top and bottom electrodes. The multilayer stack includes a memory element comprising programmable resistive memory material and has a sidewall surface. An air gap is adjacent to the sidewall surface and self-aligned to the memory element.

A memory interface controller and method to allow a processor designed and configured to operate with NOR flash and static random access memory (SRAM) memory devices to instead operate using NAND flash and synchronous dynamic random access memory (SDRAM). The system accomplishes this by caching sectors out of NAND flash into SDRAM, where the data can be randomly accessed by the processor as though it were accessing data from NOR flash / SRAM. Sectors containing data required by the processor are read out of NAND flash and written into SDRAM, where the data can be randomly accessed by the processor.

A semiconductor memory device includes a memory cell array including a plurality of memory cells, a source terminal which supplies a source potential to the memory cells, a first switching element which electrically connects the source terminal and a first power supply potential in an operation mode of the memory cells, and electrically disconnects the source terminal and the first power supply potential in a standby mode of the memory cells, a clamp MIS transistor which is series-connected between the source terminal and the first power supply potential, and clamps the source potential in the standby mode, a bias generation circuit which supplies a first bias potential to a gate terminal of the clamp MIS transistor, and a switching circuit which switches a potential of a back gate terminal of the clamp MIS transistor between a test mode and a non-test mode.

Magneto-resistive random access memory elements include a ferromagnetic layer having uniaxial anisotropy provided by elongate structures formed in the ferromagnetic film. The magnetic dipole aligns with the long axis of each structure. The structures can be formed in a variety of ways. For example, the ferromagnetic film can be applied to a seed layer having a textured surface. Alternatively, the ferromagnetic film can be stressed to generate the textured structure. Chemical mechanical polishing also can be used to generated the structures.
