Indigenous memory technology

In news

IIT Bombay researchers have developed a “memory technology” that can, in principle, revolutionise Indian industry and the many applications that need semiconductor chips, such as in the defence sector, automobiles and future aspirations in cell phone manufacturing.

Details
  • Hard disks, flash memory, etc, are examples of memory technology.
  • There is also another form of memory called the one-time programmable memory (OTP) where the memory is written once, stored for a lifetime, and retrieved and used many times.
  • This finds varied uses, one of which is in correcting faulty chips that have been mass produced for specific applications.
OTP memories
  • For instance, think of a chip that helps read off the temperature. Due to a manufacturing defect, the chip may read 100 degree Celsius as 101 degree Celsius.
  • This “offset” of 1 degree may be corrected by storing the error correction parameter in the OTP memory.
  • This is done uniquely for each chip and once stored, the memory corrects the chip’s output for its lifetime.
  • “OTP memories are also used for other purposes, mainly three: chip identity, secure information storage and chip calibration for error correction.
