Straintronics-Based Random Access Memory as Universal Data Storage Devices

Permuting Data on Random-Access Block Storage

Permutation is a fundamental operator for array data, with applications in, for example, changing matrix layouts and reorganizing data cubes. We consider the problem of permuting large quantities of data stored on secondary storage that supports fast random block accesses, such as solid state drives and distributed key-value stores. Faster random accesses open up interesting new opportunities f...

Analog and Digital Switching Characteristics of Transition Metal Oxide Based Resistive Random Access Memory (ReRAM) Devices

Transition Metal Oxide (TMO) Based Resistive Random Access Memory (ReRAM) devices have gathered significant research attention for non-volatile data storage applications. The major advantages lie in terms of scalability, low switching voltages, and process compatibility with the CMOS technologies [1, 2]. However, to take the complete benefit of this enabling technology there are several challen...

Dynamic random access memory devices based on bismuth sulfide nanoplates prepared from a single source precursor.

Semiconducting bismuth sulfide (Bi2S3) nanoplates with unique highly oriented {001} surfaces were prepared on a large scale using a novel organic precursor Bi(DTCA)3 (DTCA = carbazole-9-carbodithioic acid). The as-prepared Bi2S3 nanoplates were dispersed in dimethyl sulfoxide (DMSO) and spin-coated onto an indium tin oxide (ITO) coated glass substrate. With a simple ITO/Bi2S3/Al stacked structu...

Embedded Memory Hierarchy Exploration Based on Magnetic Random Access Memory

Static random access memory (SRAM) is the most commonly employed semiconductor in the design of on-chip processor memory. However, it is unlikely that the SRAM technology will have a cell size that will continue to scale below 45 nm, due to the leakage current that is caused by the quantum tunneling effect. Magnetic random access memory (MRAM) is a candidate technology to replace SRAM, assuming...
