eFuses: Use Cases, Benefits, And Design In The System Context
By Jens Michael Warmuth - 12 Sep, 2024 - Comments: 0

In recent years, the automotive industry has been one of the drivers of innovation in the field of electrical and electronic system safety. This is primarily due to the rapid uptake and, in some cases, already mandatory use of advanced driver assistance systems (ADAS) as well as to the first steps toward (partially) autonomous vehicles. In conventional safety systems, the off state can be as... » read more

Taming Novel NVM Non-Determinism
By Bryon Moyer - 10 Mar, 2020 - Comments: 1

New memory technologies may have non-deterministic characteristics that add calibration to the test burden — and may require recalibration during their lifetime. Many of these memories are in development as a result of the search for a storage-class memory (SCM) technology that can bridge the gap between larger, slower memories like flash and faster DRAM memory. There are several approache... » 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

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
