Weebit Nano announced an embedded ReRAM module

Weebit Nano (ASX:WBT) has completed the design and verification of embedded ReRAM module, and taped-out a test-chip for testing and qualification. “The test chip allows Weebit to demonstrate a fully functional ReRAM memory product, “that can be readily integrated into System-on-Chip,” said Weebit’s CEO, Coby Hanoch.

The ReRAM (Resistive Random Access Memory) module comprises a full sub-system in which the module is embedded. It also includes a RISC-V microcontroller (MCU), system interfaces, Static Random-Access Memory (SRAM) and peripherals. It was designed for ST 130nm process and consists of a 128Kb ReRAM array, control logic, decoders, IOs (Input/Output communication elements) and error correcting code (ECC).

Weebit expects to recieve the first silicon towards the end of 2021, and to demonstrate the module in the first quarter of 2022. Qualifications are expected to be completed by mid-2022. ReRAM is an emerging technology that combines the advantages of both DRAM and Flash: It is a non-volatile, extremely fast, low-power and can endure significantly higher number Program/Erase cycles than Flash memory.

Weebit’s ReRAM cell consists of 2 metal layers with a Silicon Oxide (SiOx) layer between them. In an initial, one-time, forming step, positive voltage is applied on the cell to form a conductive filament, and entering a Low Resistive State. After that – applying positive and negative voltages can cause the cell to move from one state to the other. For now the company is focused on the embedded applications market, delivering solutions to semiconductor customers and fabs who embed its IP into their SoCs. The long tem goal is into the broad market for discrete memory devices.

Weebit Nano raised $4.5 million to commercialize ReRAM technology

Hod Hasharon (near Tel Aviv)-based Weebit Nano, which is developing a new type of non-volatile ReRAM technology, has raised $4.5 US million through a private allotment of shares on the Australian Securities Exchange (ASX). At the moment, the company is trying to raise an additional $0.5 AUD million through a public offering. Weebit Nano’s CEO, Coby Hanoch, told Techtime that this financial round ,”Will allow us to move towards commercialization, and hopefully, within a year we’ll already be engaging in serious interactions with potential customers.”

According to the report supplied by the company to the ASX, about half of the money raised will be allocated for the development of a dedicated module for embedded systems, the company’s first target market for its ReRAM technology. “Our technology has already been proven and tested by customers. We are now developing a specific module of the memory, in order to make it suitable for the embedded systems market.”

The Best of all Possible Worlds

Approximately 20% of the amount will be allocated for the development of a component called ‘Selector’, which is designed to minimize leakage currents between the memory cells, and about 15% for transferring the technology for production at standard Fab manufacturing facilities. Weebit Nano is developing a new Resistive Random Access Memory (ReRAM), based on the use of materials that change their electrical resistance in response to electrical voltage, thus “remembering” the voltage levels after they are disconnected from the power source.

It combines the non-volatility of flash memory with the fast, low-power, and long life cycle of the volatile DRAM memory technologies. The company estimates that its prototype is 1,000 times faster and uses 1,000 times less power than flash memory, traits which make him perfect candidate for IoT, artificial intelligence, information centers and more.

Lately, Weebit Nano announced first commercial collaborations, both with the Chinese semiconductors companies, XTX and SiEn. Together, they will examine the integration of the Weebit Nano’s memory component into their’ products. “China is the largest chip consumer in the world, and is determined to build an independent semiconductors industry,” said Hanoch.
