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...

Magnetic random access memory design using rings with controlled asymmetry

Narrow permalloy ring elements with different symmetries have been investigated. Two stable states of opposite polarity at remanence and simple switching have been observed using magnetic-force microscopy. (Some figures in this article are in colour only in the electronic version)

Holographic Random Access Memory

We examine the primary challenges for building a practical and competitive holographic random access memory (HRAM) system, specifically for size, speed, and cost. We show that a fast HRAM system can be implemented with a compact architecture by incorporating conjugate readout, a pixel-matched sensor array, and a linear array of laser diodes. It provides faster random access time than hard disk ...
