Calibrate And Configure Your Power Management IC With NVM IP
By Synopsys - 09 Feb, 2022 - Comments: 0

Power Management Integrated Circuits (PMICs) are the first to turn on and the last to turn off in a system. They perform the task of delivering the right voltage to component chips by regulating or boosting the voltage levels to the component chips. Some PMICs are configured once at the factory and an area-efficient OTP NVM is the best choice. When a PMIC is expected to be re-configured mult... » read more

Making Sense Of PUFs
By Bryon Moyer - 07 May, 2020 - Comments: 3

As security becomes a principal design consideration, physically unclonable functions (PUFs) are seeing renewed interest as new players emerge onto the market. PUFs can play a central role in hardware roots of trust (HRoTs), but the messaging in the market can make it confusing to understand the different types of PUF as well as their pros and cons. PUFs leverage some uncertain aspect of som... » read more

Non-Volatile Memory Tradeoffs Intensify
By Ann Mutschler - 22 Jan, 2020 - Comments: 0

Non-volatile memory is becoming more complicated at advanced nodes, where price, speed, power and utilization are feeding into some very application-specific tradeoffs about where to place that memory. NVM can be embedded into a chip, or it can be moved off chip with various types of interconnect technology. But that decision is more complicated than it might first appear. It depends on the ... » read more

The Case For Antifuse OTP NVM For Secure & Reliable SoCs
By Krishna Balachandran - 10 Jan, 2019 - Comments: 2

Non-volatile memory (NVM) is used for persistent data and secure code storage in a wide range of electronic systems in automotive, mil-aero, power management IC (PMIC), mobile, and Internet of Things (IoT) markets. NVM comes in different flavors including multiple-time programmable (MTP), few-time programmable (FTP), and one-time programmable (OTP). When determining the ideal NVM solution, desi... » read more

New Opportunities For OTP NVM
By Melissa Kirschner - 01 Nov, 2018 - Comments: 0

By 2020 more than 50 billion devices will be connected to the Internet, according to Cisco’s latest forecast. Smartphone traffic will exceed PC traffic and broadband speeds will nearly double by 2021. And by the next Winter Olympics (Beijing 2022), 1 trillion networked sensors could be embedded in the world around us. While tech experts offer slightly different projections of actual numbers,... » read more

Intelligent Compute Engines Driving Today’s Automobiles Need Better Security
By Paolo Piacentini - 06 Apr, 2017 - Comments: 0

Driving a modern car or truck today is like driving a complex computer system which has the capability to transport people and freight from a geographic point to another through the road infrastructure and, to do so, it just happens it has an engine and wheels. With automotive systems moving towards consolidation of workloads, there is a need and benefit of having faster networking throughpu... » read more

The Benefits Of Antifuse OTP
By Nick Chen - 19 Dec, 2016 - Comments: 3

One-time programmable (OTP) memory is a type of non-volatile memory (NVM) that commonly comprises of electrical fuse (eFuse) and antifuse. The advantages of OTP memory over multi-time programmable (MTP) memory, such as EEPROM or flash memory, are smaller area and no additional wafer processing steps. Therefore, for many low-cost applications, the OTP memory is used to replace the MTP memory. ... » read more

In An Election Year: OTP For IoT
By Lee Sun - 06 Oct, 2016 - Comments: 0

Borrowing from this year’s hottest topic –– the Presidential Election –– let’s nominate one-time programmable (OTP) embedded memory for the Internet of Things (IoT). It’s sure to be the winner for any number of reasons, but most likely it is because of its built-in security features. As a memory-on-chip technology, antifuse OTP is paving the way for IoT designers to come up with n... » read more

The Growing Need For OTP
By Lee Sun - 04 Aug, 2016 - Comments: 0

Historically, when someone from our industry uses the acronym OTP, or one-time programmable, they think of eFuse, invented by IBM in 2004.  Using electromigration, IBM was able to program a fuse without damaging other parts of the chip. In this way, fuses could dynamically alter the configuration of a chip after it was manufactured. Applications range from analog trimming and calibration to re... » read more

One-Time-Programmable Memories For IoT Security
By Paolo Piacentini - 07 Apr, 2016 - Comments: 0

Security in the IoT space is an issue of major concern. Hackers are attacking IoT devices across all layers of the infrastructure, from the application layer down to protocol, to the physical and deep into the IoT devices. I intend to focus on vulnerability prevention for IoT devices at the lowest level: memory structure and key storage. I conclude with indicating highly important features a... » read more
