Weebit Nano First Wafers

Weebit Nano has received from manufacturing the first silicon wafers that integrate its embedded ReRAM module inside complete subsystem demonstration (demo) chips.

The chips will be used for testing and characterisation, as well as for demonstration to potential customers.

The demo ICs 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 successfully manufacture the demo wafers.

The wafers will now be skiced, packaged, 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 progressing on schedule.

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 circuitry that significantly enhances the memory array’s technical parameters including speed, retention, and endurance.

It is  customisable and will provide a foundation for Weebit’s future ReRAM compiler.

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.
