Compared to PRAM, ReRAM operates at a faster timescale (switching time can be less than 10 ns), while compared to MRAM, it has a simpler, smaller cell structure (less than 8F² MIM stack). A vertical 1D1R (one diode, one resistive switching device) integration can be used for crossbar memory structure to reduce the unit cell size to 4F² (F is ...
2003 — A 128 kbit MRAM chip was introduced, manufactured with a 180 nm lithographic process; 2004 June — Infineon unveiled a 16-Mbit prototype, manufactured with a 180 nm lithographic process; September — MRAM becomes a standard product offering at Freescale. October — Taiwan developers of MRAM tape out 1 Mbit parts at TSMC.
Data reliability is guaranteed in F-RAM even in a high magnetic field environment compared to MRAM. Cypress Semiconductor's [ 16 ] F-RAM devices are immune to the strong magnetic fields and do not show any failures under the maximum available magnetic field strengths (3,700 Gauss for horizontal insertion and 2,000 Gauss for vertical insertion).
A memristor (/ ˈ m ɛ m r ɪ s t ər /; a portmanteau of memory resistor) is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkage.It was described and named in 1971 by Leon Chua, completing a theoretical quartet of fundamental electrical components which also comprises the resistor, capacitor and inductor.
CBRAM vs. metal-oxide ReRAM [ edit ] CBRAM differs from metal-oxide ReRAM in that for CBRAM metal ions dissolve readily in the material between the two electrodes, while for metal-oxides, the material between the electrodes requires a high electric field causing local damage akin to dielectric breakdown , producing a trail of conducting defects ...
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 ...
This is strictly the same technology as "Phase-change memory". Specific RRAM content should be merged into the "Phase-change memory" page. Disagree: A reading of patent 6946702 suggests phase-change memory and the resistance random access memory described in the patent use a fundamentally different memory storage element.
Examples include the ubiquitous 28-pin 8K × 8 and 32K × 8 chips (often but not always named something along the lines of 6264 and 62C256 respectively), as well as similar products up to 16 Mbit per chip. Synchronous – all timings are initiated by the clock edges. Address, data in and other control signals are associated with the clock signals.
