In this case, for a 3D-ReRAM 1TNR array, with a column of N ReRAM cells situated above a select transistor, only the intrinsic nonlinearity of the HRS is required to be sufficiently large, since the number of vertical levels N is limited (e.g., N = 8–32), and this has been shown possible for a low-current ReRAM system.
RRAM (ReRAM) works by changing the resistance across a dielectric solid-state material often referred to as a memristor. ReRAM involves generating defects in a thin oxide layer, known as oxygen vacancies (oxide bond locations where the oxygen has been removed), which can subsequently charge and drift under an electric field.
Retention and endurance characteristics. a) Retention data for a 20 μm gate-length cell. b) S-D current difference (∆IS-D) for the >24 h retention plotted on a log scale.
Weebit Nano produces resistive random-access memory (ReRAM) which is a specialized type of random-access memory that maintains its state (and data) even if the device loses power. ReRAM is used in specialized environments where data must be preserved despite environmental challenges, such as aerospace, transportation and medical environments.
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...
Development of 3D XPoint began around 2012. [8] Intel and Micron had developed other non-volatile phase-change memory (PCM) technologies previously; [note 1] Mark Durcan of Micron said 3D XPoint architecture differs from previous offerings of PCM, and uses chalcogenide materials for both selector and storage parts of the memory cell that are faster and more stable than traditional PCM ...
High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...
History. Crossbar was founded in 2010, by George Minassian, Hagop Nazarian, and Wei Lu. [1] [3] As part of the University of Michigan Tech Transfer program, in 2010, ...
