Weebit Nano Restricted (Weebit), a number one developer and licensor of superior reminiscence applied sciences for the worldwide semiconductor business, and tier-1 semiconductor foundry DB HiTek have taped-out (launched to manufacturing) an indication chip integrating Weebit’s embedded Resistive Random-Entry Reminiscence (ReRAM) module in DB HiTek’s 130 nm Bipolar-CMOS-DMOS (BCD) course of. The extremely built-in demo chips can be used for testing and qualification forward of buyer manufacturing, whereas demonstrating the efficiency and robustness of Weebit’s expertise.
This vital milestone within the collaboration between Weebit and DB HiTek (beforehand introduced on 19 October 20231) was accomplished on-schedule as a part of the expertise switch course of. The businesses are working to make Weebit ReRAM out there to DB HiTek clients for integration of their methods on chips (SoCs) as embedded non-volatile reminiscence (NVM), and purpose to have the expertise certified and prepared for manufacturing within the second quarter of the 2025 calendar 12 months. Weebit ReRAM is on the market now to pick out DB HiTek clients for design prototyping forward of manufacturing.
DB HiTek’s 130 nm BCD course of is right for analog, mixed-signal and high-voltage designs in purposes reminiscent of client, industrial, and IoT units. For these purposes, Weebit ReRAM offers a cost- efficient, low-power NVM that’s simple to combine and has confirmed glorious retention at excessive temperatures. ReRAM provides vital benefits over flash for BCD processes as a result of it’s a back-end- of-line (BEOL) expertise which doesn’t require vital course of tuning. Weebit ReRAM additionally offers greater density and endurance in comparison with typical Multi-Time Programmable (MTP) applied sciences.
Coby Hanoch, CEO of Weebit Nano, mentioned: “This milestone confirms we’re continuing in the direction of qualification of our ReRAM in DB HiTek’s BCD course of on schedule, making the expertise out there to this main foundry’s in depth buyer base. We’re already in early adopter discussions with a number of DB HiTek clients who’re fascinated about integrating ReRAM of their SoCs. One space of curiosity is sensible
energy administration built-in circuits (PMICs), the place integrating the PMIC with the microcontroller (MCU) on one die can result in efficiency, safety, energy and value benefits.”
Ki-Seog Cho, CEO, DB HiTek, mentioned: “A lot of our clients, particularly these with energy administration and high-voltage designs, need to acquire the benefits of embedded ReRAM. Weebit ReRAM will
present clients utilizing our 130 nm BCD course of with a low-power, cost-effective and high-density NVM. And by shifting from a two-chip to a single-die resolution, they will save price and energy, and scale back
complexity and dimension. We’ve got an excellent working relationship with Weebit, and we’re excited to proceed this very promising collaboration.”
As soon as certified, DB HiTek will add Weebit’s reminiscence module to its BCD 130 nm Course of Design Package (PDK). DB HiTek clients can use the usual modules within the PDK or have modules custom-made for his or her wants.
The demonstration chip features a 1 Mb ReRAM module that may be scaled to different densities as wanted. This fully-integrated module additionally contains all mandatory management logic, good algorithms, decoders, IOs (Enter/Output communication components) and error correcting code (ECC). It’s designed with distinctive patent-pending analog and digital circuitry working good algorithms that considerably improve the reminiscence array’s technical parameters. This ReRAM module is additional built-in into the demo chip, comprising a full sub-system for embedded purposes, together with the Weebit ReRAM module, a RISC-V MCU, SRAM, peripherals and system interfaces together with SPI, UART, JTAG and GPIO.
This announcement has been authorised for launch by the Board of Weebit Nano Restricted.
