What is the acronym RRAM?
RRAM stands for Resistive Random Access Memory. Read more in our Guide to ReRAM and RRAM.
What is the difference between RRAM and ReRAM?
RRAM and ReRAM refer to the same technology. TSMC calls it ‘RRAM’. Most of the industry says ‘ReRAM’. There’s no technical difference.
What are the different types of ReRAM / RRAM?
ReRAM (RRAM) is a non-volatile memory (NVM) technology that stores data by changing the resistance of a memory cell. All types of ReRAM are known for their high performance, low power consumption, and ability to scale to advanced processes. The differences are generally in terms of their switching mechanisms and materials, which can translate to differences in complexity […]
How does Weebit ReRAM / RRAM work?
Weebit’s oxide-based ReRAM (OxRAM) cell consists of a metal oxide switching layer between two electrodes. An initial forming step creates a conductive filament. Applying voltage pulses forms or ruptures this filament, switching the cell between a Low Resistive State (LRS) and High Resistive State (HRS) to store binary data. Because data is stored as resistance […]
What is embedded ReRAM / RRAM?
Embedded Resistive RAM (ReRAM or RRAM) is a non-volatile memory integrated as IP within a system-on-chip (SoC). Unlike embedded flash, ReRAM is implemented in the back end of line (BEOL), enabling scaling below 28nm without impacting front-end analog devices. It integrates into standard CMOS flows using common fab materials, supporting cost-efficient manufacturing and simplified process […]
How does ReRAM technology contribute to energy efficiency and sustainability in electronic devices?
Weebit ReRAM is more environmentally friendly than other types of NVM. It doesn’t require any rare earth materials, doesn’t pose any contamination risk, and doesn’t require dedicated clean room space. It also requires fewer masks and fewer steps in the fab (both vs. MRAM and embedded flash), using less resources altogether. Because it consumes less power and requires fewer resources to be […]
What is ReRAM (Resistive RAM) technology?
ReRAM (resistive RAM, also called RRAM) is a non-volatile, extremely fast, low-power and cost-effective non-volatile memory (NVM) technology that can endure a significantly higher number of Program/Erase cycles than flash memory. The Weebit oxide-based ReRAM (OxRAM) cell is comprised of a thin oxide switching layer between two electrodes. Resistance can be programmed using electric voltage. Read more about ReRAM in […]
