Weebit Nano and DB HiTek tape-out ReRAM module in DB HiTek’s 130nm BCD process
2024年7月31日 - 7:17AM
Weebit Nano Limited (
ASX:WBT) (Weebit), a
leading developer and licensor of advanced memory technologies for
the global semiconductor industry, and tier-1 semiconductor foundry
DB HiTek have taped-out (released to manufacturing) a demonstration
chip integrating Weebit’s embedded Resistive Random-Access Memory
(ReRAM) module in DB HiTek’s 130nm Bipolar-CMOS-DMOS (BCD) process.
The highly integrated demo chips will be used for testing and
qualification ahead of customer production, while demonstrating the
performance and robustness of Weebit’s technology.
This important milestone in the collaboration between Weebit and
DB HiTek (previously announced on 19 October 2023) was completed
on-schedule as part of the technology transfer process. The
companies are working to make Weebit ReRAM available to DB HiTek
customers for integration in their systems on chips (SoCs) as
embedded non-volatile memory (NVM), and aim to have the technology
qualified and ready for production in the second quarter of the
2025 calendar year. Weebit ReRAM is available now to select DB
HiTek customers for design prototyping ahead of production.
DB HiTek’s 130nm BCD process is ideal for analog, mixed-signal
and high-voltage designs in applications such as consumer,
industrial, and IoT devices. For these applications, Weebit ReRAM
provides a cost-effective, low-power NVM that is easy to integrate
and has proven excellent retention at high temperatures. ReRAM
offers significant advantages over flash for BCD processes because
it is a back-end-of-line (BEOL) technology which does not require
significant process tuning. Weebit ReRAM also provides higher
density and endurance compared to conventional Multi-Time
Programmable (MTP) technologies.
Coby Hanoch, CEO of Weebit
Nano, said: “This milestone confirms we are
proceeding towards qualification of our ReRAM in DB HiTek’s BCD
process on schedule, making the technology available to this
leading foundry’s extensive customer base. We’re already in early
adopter discussions with several DB HiTek customers who are
interested in integrating ReRAM in their SoCs. One area of interest
is smart power management integrated circuits (PMICs), where
integrating the PMIC with the microcontroller (MCU) on one die can
lead to performance, security, power and cost advantages.”
Ki-Seog
Cho, CEO, DB
HiTek, said: “Many of our
customers, especially those with power management and high-voltage
designs, are looking to gain the advantages of embedded ReRAM.
Weebit ReRAM will provide customers using our 130nm BCD process
with a low-power, cost-effective and high-density NVM. And by
moving from a two-chip to a single-die solution, they can save cost
and power, and reduce complexity and size. We have a great working
relationship with Weebit, and we’re excited to continue this very
promising collaboration.”
Once qualified, DB HiTek will add Weebit’s memory module to its
BCD 130nm Process Design Kit (PDK). DB HiTek customers can use the
standard modules in the PDK or have modules customized for their
needs.
The demonstration chip includes a 1Mb ReRAM module that can be
scaled to other densities as needed. This fully-integrated module
also includes all necessary control logic, smart algorithms,
decoders, IOs (Input/Output communication elements) and error
correcting code (ECC). It is designed with unique patent-pending
analog and digital circuitry running smart algorithms that
significantly enhance the memory array’s technical parameters. This
ReRAM module is further integrated into the demo chip, comprising a
full sub-system for embedded applications, including the Weebit
ReRAM module, a RISC-V MCU, SRAM, peripherals and system interfaces
including SPI, UART, JTAG and GPIO.
This announcement has been authorized for release by the Board
of Weebit Nano Limited.
