Mixed-Signal, Analog and Power ICs

Analog ICs represent a diverse set of technologies including sensors, power management ICs (PMICs), mixed-signal ICs, RF, MEMS, and others. These devices increasingly require embedding low-density NVM for different purposes. First, such mixed signal designs require specialized NVM to store trimming and configuration data, as well as unique IDs. These should be programmable to allow product variations, and should be field upgradeable as well.

In addition, some analog and power management designs today require the integration of a microcontroller (MCU) for added intelligence, including smart sensing and measurement on end nodes in areas such as medical and fitness devices, industrial automation and other ultra-low power IoT applications. These highly integrated devices not only need to store data and boot code, but must also run firmware updates, requiring high-performance, low-power NVM.

Analog and mixed-signal ICs need to support many device components, most of which are built in the Front-end-of-line (FEOL) of the manufacturing process, and they must support many process nodes and derivatives. Since embedded flash is also integrated in FEOL, companies must often make compromises with power and analog components in order to accommodate flash on the same wafer. This leads to degraded performance, larger size, and higher cost.

ReRAM is integrated in the Back-end-of-line (BEOL) of the manufacturing process, allowing full optimization of such components, so there is no impact on design rules. This also simplifies adopting ReRAM in a new fab as it can be adopted once for a geometry and it will work with all the different variants of that geometry, unlike flash which needs to be adapted to each variant.

As a low-cost, high-performance, highly scalable BEOL technology, Weebit ReRAM enables key requirements for embedded NVM in analog ICs.
