FeRAM-embedded ASIC/ASSP

About FeRAM-embedded ASIC/ASSP

RAMXEED designs and develops ASIC (Application Specific Integrated Circuits, custom LSI products) and ASSP (Application Specific Standard Products) embedded with FeRAM non-volatile memory. FeRAM can be integrated with CMOS processes, and can be combined with logic circuits and analog circuits to form a single chip.
With know-how accumulated through over 20 years of experience in designing and developing FeRAM-embedded LSIs, we have developed a large number of highly reliable, high-performance system LSIs, such as RFID LSIs and IC cards.
We can provide one-stop IC development services, from specification design to manufacturing, according to customer requirements. Let’s create new value together with FeRAM.

Reasons to Choose FeRAM

Do you have any of these issues?

Unable to differentiate from competitors and can only compete on price
Short data retention periods and many work hours required for frequent maintenance
Unable to extend battery life as much as desired
Combination of various chips leads to large size and inflated costs
Systems are unstable and vulnerable to data loss, power outages, and physical shocks

FeRAM-embedded ASICs/ASSPs
can solve your challenges!

  • Surpass conventional memory performance

    Create highly unique ICs with numerous features that surpass conventional memory, such as high-speed writing, low power consumption, and environmental resistance.

  • Long-term data retention with non-volatility

    There is no need for frequent data retrievals, and the frequency of maintenance can be reduced.

  • Amazingly low power consumption

    Useful for devices where battery life is a critical factor, such as wearable devices.

  • Smaller chip sizes

    Functions such as MCU, ROM, and RAM can be narrowed down, enabling only the necessary functionality to be placed on a single chip.
    Capacity per unit area is more than ten times that of MIM and MOS, and area can be reduced using ferro capacity.

  • Outstanding stability

    Prevents data losses caused by EEPROM and FLASH, and enables the construction of highly reliable systems that are resistant to power outages and physical shocks.

Differences between ASIC and ASSP

Both ASICs and ASSPs are integrated circuits (ICs) designed to achieve specific functions, but there are some key differences.

  • ASIC(Application Specific Integrated Circuit) are ICs that are specifically designed for a specific customer or application. This allows the emphasis to be placed on design for performance and cost-efficiency rather than versatility.
  • ASSP(Application Specific Standard Product) are ICs that are universally designed for specific applications. Since they are more versatile than ASICs, they are also suitable for small-batch production.

We propose both ASICs and ASSPs according to the specific needs of our customers.

Security and authentication

  • Authentication ICs

    Customers wish to protect products from counterfeiting, and protect their safety and reliability.

    Reasons to Choose FeRAM

    RAMXEED’s unique crypto-less authentication has high security strength because there is no key information to be stolen, and protects customer products from the threat of counterfeiting. We deliver ICs that can be used for a long time with peace of mind, and reduce the burden of development placed on our customers.

  • IC cards

    It is necessary to maintain communication even with unstable contactless power supplies. High-speed operation and short-term data updates are required for security.

    Reasons to Choose FeRAM

    RF technology optimized for high-speed rewriting and low FeRAM consumption improves operating speeds and communication response, speeding up overall system operation and reducing user stress.

Wireless power supply and communication

  • Wireless power supply sensing

    Wireless power supply and communication technologies developed in RFIDs and IC cards combined with analog sensing technologies, achieve wireless power supply sensing without batteries.

    Reasons to Choose FeRAM

    Low power consumption for write operations, stable communication and sensing.

  • Sterile RFIDs

    • Improve efficiency of usage history management for medical devices with RFIDs.
    • Data must be readable even after equipment sterilization.
    • Customers wish to perform sterilization by irradiation, which is highly convenient and does not require high heat or gas.

    Reasons to Choose FeRAM

    Radiation resistance and low power consumption enable RF communication after convenient sterilization by irradiation, reducing equipment management workload

Analog energy harvesting

  • Battery-free rotary encoders

    • Customers wish to count the number of motor revolutions even when there is no power supply, due to power outage at the factory.
    • In the past, a gear-based system was employed in Europe, and in Asia SRAM with a battery was used to count the number of revolutions.

    Reasons to Choose FeRAM

    • The amount of power required for write operations is extremely low compared to other memory types, and can be operated by energy harvesting from rotation in the rotary encoder.
    • Energy harvesting with FeRAM is attracting attention as a solution to replace gear-type systems, which are prone to breakdowns, and battery-powered SRAM systems, which are costly to maintain.
