Virage Logic Corp.'s next-generation embedded non-volatile memory called NOVeA provides a multi-programmable embedded memory that the company says is key in applications requiring sophisticated security and digital rights management (DRM) capabilities such as flash memory cards, DVD players and recorders, STBs and RFID tags.

CMOS logic process
The NOVeA, based on the existing NOVeA bit cell, addresses the requirements of consumer and secure applications. NOVeA can be manufactured on a standard CMOS logic process. This product expands the density to 16Kbits, allowing EEPROM replacement in many applications. As in previous generations, NOVeA requires no additional masking, process steps or process modifications.

At less than 50 per cent the area of previous NOVeA versions, this offering provides developers of cost-sensitive consumer and secure applications with dramatic area savings. Additionally, the NOVeA consumes roughly 30 per cent less power than previous NOVeA versions, important in consumer applications and in passive RFID tags, where the read distance is governed by power consumption. With its 100 per cent cell redundancy architecture, NOVeA also provides designers with high yield and reliability.

OTP apps
One-time programmable applications, such as programmable fuses, device ID or device options can also use NOVeA. Unlike pure one time programmable solutions, NOVeA offers 100 per cent verification at test. Pure one time programmable devices are not verified at test if they are shipped unprogrammed to the end customer application. NOVeA allows for device programming and thus verifies at test before erasing and shipping it unprogrammed to end applications. NOVeA is reprogrammable in-system up to 100,000 times and has specified endurance for 10 years at 125°C.

The next-generation NOVeA is available today. Pricing varies depending on process node: 180nm, 130nm or 90nm.
