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 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.
