First silicon demonstration wafers with integrated embedded ReRAM module

1 min read

Weebit Nano has received the first silicon wafers that integrate its embedded Resistive Random-Access Memory (ReRAM) module inside complete subsystem demonstration (demo) chips.

According to the company, a developer of next-generation memory technologies, these highly integrated chips will now be used for testing and characterisation, as well as for demonstration to potential customers.

In addition, the demo chips will allow customers to run applications to test Weebit’s ReRAM technology ahead of potential commercial orders and volume production for their specific chips.

Weebit worked with its development partner CEA-Leti to manufacture the demo wafers, which will now be sliced into chips, packaged, and then tested, characterised and qualified. Chips based on this design will be used for the qualification process in SkyWater Technology’s US production fab. The transfer of Weebit’s embedded ReRAM technology to SkyWater Technology’s production fab is said to be progressing on schedule.

Commenting Coby Hanoch, CEO of Weebit Nano, said, “The demo chips integrating Weebit’s ReRAM module will support the adoption of our technology by potential customers looking to address the shortcomings of flash memory. We will now be able to provide customers with a fully functional ReRAM technology that can be readily integrated into their Systems-on-Chips [SoCs] to facilitate the design of new embedded products that are moving beyond flash.”

Weebit’s embedded ReRAM module includes a 128Kb ReRAM array, control logic, decoders, IOs (Input/Output communication elements) and error correcting code (ECC). It is designed with patent-pending analogue and digital smart circuitry that significantly enhances the memory array’s technical parameters including speed, retention, and endurance.

In addition to Weebit’s ReRAM module, the demo chip includes a RISC-V microcontroller (MCU), system interfaces, SRAM and peripherals – altogether comprising a full sub-system for embedded applications.
