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

Sony to aims to commercialize 128GB and 256GB ReRAM drives in 2020

Sony announced that it is accelerating its RRAM ("Cross Point ReRAM") development with an aim to commercialize it in 2020. Sony says that its ReRAM will be cheaper than NAND, and also faster, consumer less power and heat. Sony's efforts at this stage are to develop a smart low-power ReRAM controller, reduce the power consumption and manage the thermal issues.

NTU and GlobalFoundries to co-develop RRAM memories on 12" wafers

Singapore's Nanyang Technological University (NTU Singapore) and GlobalFoundries announced a partnership to jointly research next-generation RRAM memories. The two partners will invest $88 million USD with an aim to demonstrate RRAM memory devices produced on 12-inch wafers.

NTU and GF-Singapore are already collaborating on spintronics - the study of electron spin and its applications, including MRAM memory (NTU and GF are founding members of the Singapore Spintronics Consortium. In this new ReRAM project, 16 researchers will work together to research areas such as circuit design for next-generation smart devices and chip packaging for advanced IoT applications.

Strategic Elements to showcase its transparent RRAM memory by the end of 2019

Strategic Elements announced that it is developing a transparent memory demonstrator, in collaboration with UNSW, CSIRO and the VTT Group. The demonstrator will include a 10.4" transparent display and SER's own printable transparent Nanocube Memory Ink (RRAM memory).

The demonstrator is transparent until touched, which then waits for a user to press the authentication code. This demo will showcase the possibility of print functional memory on transparent glass. The demonstrator is due in Q4 2019 (the main delay, according to SER, is the sourcing of the transparent display).

Crossbar announces an RRAM-based AI accelerator chip

RRAM developer Crossbar announced a new SPI-based AI accelerator chip, which it calls XPU. The chip targets a specific lookup phase during AI calculations and contains an RRAM memory device and a programmable coparator.
