RRAM-Info: the RRAM experts

RRAM-Info is a news hub and knowledge center for Resistive RAM technologies.

Resistive RAM is a non-volatile computer memory that uses materials that change their resistance - or memristors. RRAM is still in its early stages, but it may enable fast, efficient and small memory chips

Weebit Nano receives the first RRAM-enabled silicon wafers from SkyWater Technology

Israel-based RRAM developer Weebit Nano announced that it has received the silicon wafers from SkyWater Technology, with embedded Weebit RRAM. The company says this is an important step as its technology is now proven with standard tools and a mature process flow, which makes it easy for customers to dopt its technology.

The silicon SkyWater RRAM-enabled wafers will be sliced into chips, packaged, and then tested and qualified. The chips, which were manufactured in SkyWater’s 130nm CMOS process, will be used for customer demonstrations, testing and prototyping ahead of commercial orders and volume production, allowing customers to confidently start designing SoCs using these ReRAM modules.

Weebit Nano shows a demo of its RRAM neuromorphic memory at Flash Memory Summit

Israel-based RRAM developer Weebit Nano demonstrated (together with its partner, CEA-Leti) how its RRAM can provide an exciting new solution for artificial intelligence applications using spiking neural networks, at the Flash Memory Summit:

Neuromorphic computing makes it possible to emulate the brain’s natural operation. Using RRAM, this emulation is much more efficient than today’s simulations, consuming orders of magnitude less power, to allow sophisticated AI at a fraction of the power consumed by today’s systems. This is because the ReRAM (RRAM) cell has physical and functional similarities to a biological brain synapse.

Weebit demonstrated its first operational crossbar RRAM array

Israel-based RRAM developer Weebit Nano announced that together with CEA-Leti iit has demonstrated its first operational crossbar arrays that combine its ReRAM technology with a selector.

Weebit says that that is is a key milestone on the company's path to creating standalone memory chips. The company's RRAM crossbar arrays were developed using a 1S1R (one selector one resistor) architecture to enable the higher density needed for discrete chips. Weebit's arrays can be stacked in 3D layers to deliver higher densities.

CrossBar sees RRAM used for FTP and OTP memory applications

CrossBar says that its partners are now starting to use its RRAM memory technology for few-time programmable (FTP) and one-time-programmable (OTP) NVM applications. This is in addition to CrossBar's "traditional" MTP non-volatile memory and PUF security applications.

CrossBar says that this new applications demand can be met with its current technology, but the company also offers to optimize its RRAM for FTP and OTP applications, which will significantly increase memory density and reduce the cost.
