Dynamic computing random access memory

Dynamic Computing Random Access Memory

The present von Neumann computing paradigm involves a significant amount of information transfer between a central processing unit and memory, with concomitant limitations in the actual execution speed. However, it has been recently argued that a different form of computation, dubbed memcomputing (Di Ventra and Pershin 2013 Nat. Phys. 9 200-2) and inspired by the operation of our brain, can res...

Dynamic Random Access Memory: A Survey

The increasing gap between processor speed and main memory latency has accelerated the development of various innovative architectures from dynamic random access memory(DRAM) vendors. We note that recent DRAM innovations have taken place along three dimensions: reduce access latency, develop new interfaces to achieve higher bandwidth, and add simple logic to the DRAM core for application specii...

Carbon nanotube-based nonvolatile random access memory for molecular computing

A concept for molecular electronics exploiting carbon nanotubes as both molecular device elements and molecular wires for reading and writing information was developed. Each device element is based on a suspended, crossed nanotube geometry that leads to bistable, electrostatically switchable ON/OFF states. The device elements are naturally addressable in large arrays by the carbon nanotube mole...

Prospects for a Quantum Dynamic Random Access Memory (Q-DRAM)

Compared to quantum logic gates, quantum memory has received far less attention. Here, we explore the prognosis for a solid-state, scalable quantum dynamic random access memory (Q-DRAM), where the qubits are encoded by the spin orientations of single quantons in exchange-decoupled quantum dots. We address, in particular, various possibilities for implementing refresh cycles. ∗Corresponding auth...
