sureCore to add support for Intrinsic's RRAM memory to its SureFit custom design service

UK-based RRAM developer Intrinsic Semiconductor Technologies (Intrinsic) announced a collaboration with sureCore, to accelerate the time to market for its RRAM technology. Intrinsic says that its technology will assist SoC developers looking for embedded memory solutions in 22 nm or smaller nodes. 

sureCore will add Intrinsic's MRAM technology into its SureFIT Custom Design Service. Intrinsic says that both microcontrollers and evolving AI architectures using Intrinsic RRAM will deliver higher performance at lower power envelopes than those realized using off-chip flash.

Under the agreement, DB HiTek has licensed Weebit ReRAM for its customers to integrate as embedded non-volatile memory. Weebit ReRAM technology will be available in DB HiTek’s 130nm Bipolar-CMOS-DMOS (BCD) process, which is used in analog, mixed-signal, and power designs in consumer, industrial and other IoT devices. DB HiTek also has the option to use Weebit ReRAM for other process nodes.

The fund raising took part through the placements of 12 million new shares to international institutional investors, as well as an oversubscribed share purchase plan (SPP) to existing shareholders.

In early 2023 Weebit taped-out demonstration chips integrating its embedded RRAM module in an advanced 22nm FD-SOI process technology. In November 2022 the company announced that it has received the first silicon wafers from SkyWater Technology, with embedded Weebit RRAM.

Weebit Nano taped-out its first 22 nm demo RRAM chip

Israel-based RRAM developer Weebit Nano announced that it has taped-out (released to manufacturing) demonstration chips integrating its embedded RRAM module in an advanced 22nm FD-SOI (fully depleted silicon on insulator) process technology.

Infineon to adopt TSMC's embedded RRAM in its next-gen Aurix microcontrollers

Infineon says that its next generation Aurix TC4x microcontrollers will adopt RRAM memory, instead of the traditional embedded flash. The company expects the first samples of such chips to ship to customers before the end of 2023.

Infineo's next-gen Aurix chips will be produced at Taiwan Semiconductor Manufacturing Co (TSMC), using its 28nm CMOS process. The company says that RRAM memory will be more energy efficient at 28nm compared to the currently-used embedded flash memories. The RRAM memory will also enable higher disturb immunity and it allows for bit-wise writing without need for erase, which allows for superior performance over embedded flash. The cycling endurance and data retention are comparable with flash.

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.

This is the first tape-out of Weebit's technology to a production fabrication. The technology will be available on SkyWater’s 130nm CMOS process, which is suitable for applications such as analog, power management, automotive, IoT and medical. Weebit says that its chips are designed with unique patent-pending analog and digital smart circuitry running smart algorithms, thereby significantly enhancing the memory array’s technical parameters

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.
