2) These OTP memories are used for chip identity, secure information storage and chip calibration for error correction.

Which of the statements given above is/are correct?

a)  1 only

b) 2 only

c)   Both 1 and 2

d) Neither 1 nor 2

Answer: (c) Both 1 and 2

Explanation:

In NEWS: Indigenous memory technology moves from lab to fab

●    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.

●    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. Hence statement 1 is correct

●    This finds varied uses, one of which is in correcting faulty chips that have been mass produced for specific applications.

●    OTP memories are also used for other purposes, mainly three: chip identity, secure information storage and chip calibration for error correction. Hence statement 2 is correct

●    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.

How does it work?

●        To store the correction value, the researchers used eight memory cells, each of which would store one “bit” (that is a value of zero or one).

●        Each of the memory cells consist of an ultrathin silicon dioxide layer which is 10-15 atomic layers thick.

●        This is deposited uniformly over a dinner plate–sized eight-inch silicon wafer to form millions of nanoscale capacitors.

●        The pristine silicon dioxide layer is insulating, passing a very low current [which in digital electronics is read as a “0”].

●        A nanoscale lightning is generated of 3.3 volts to blow the capacitor, leading to a short circuit that produced high current [this is a “1”].

●        Thus, the OTP memory remembers either the “0” state or “1” state through its lifetime.

2. Consider the following statements

1) Dark energy is an unknown form of energy that affects the universe on a large scale.

2) While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe.

Which of the statements given above is/are correct?

a)  1 only

b) 2 only

c)   Both 1 and 2

d) Neither 1 nor 2

Answer: (c) Both 1 and 2

Explanation:

In NEWS: Explained: What is dark energy, and have scientists finally detected it?

●        The XENON1T experiment is the world’s most sensitive dark matter experiment and was operated deep underground at the INFN Laboratori Nazionali del Gran Sasso in Italy.

●        The finding also suggests that experiments like XENON1T, which are designed to detect dark matter, could also be used to detect dark energy.

What is Dark Energy?

●        Dark energy is an unknown form of energy that affects the universe on the largest scalesHence statement 1 is correct

●        The first observational evidence for its existence came from measurements of supernovae, which showed that the universe does not expand at a constant rate; rather, the expansion of the universe is accelerating.

●        Prior to these observations, it was thought that all forms of matter and energy in the universe would only cause the expansion to slow down over time.

●        Measurements of the cosmic microwave background suggest the universe began in a hot Big Bang, from which general relativity explains its evolution and the subsequent large-scale motion.

●        Without introducing a new form of energy, there was no way to explain how an accelerating universe could be measured.

●        Everything we see – the planets, moons, massive galaxies, you, me, this website – makes up less than 5% of the universe.

●        About 27% is dark matter and 68% is dark energy.

●        While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe. Hence statement 2 is correct

Answer: (b) 2 only

Explanation:

In NEWS: An institution’s right to govt. aid is not a fundamental right: SC

●        The right of an institution, whether run by a majority or minority community, to get government aid is not a fundamental right. Both have to equally follow the rules and conditions of the aid, the Supreme Court held in a judgment. Hence statement 1 is not correct

●        Whether it is an institution run by the majority or the minority, all conditions that have relevance to the proper utilisation of the grant-in-aid by an educational institution can be imposed.

●        All that Article 30(2) states is that on the ground that an institution is under the management of a minority, whether based on religion or language, grant of aid to that educational institution cannot be discriminated against, if other educational institutions are entitled to receive aid

●        The Bench clarified that if the government made a policy call to withdraw aid, an institution cannot question the decision as a “matter of right”.

●        A grant of government aid comes with accompanying conditions. An institution is free to choose to accept the grant with the conditions or go its own way

About ARTICLE 30

Right of minorities to establish and administer educational institutions

●        All minorities, whether based on religion or language, shall have the right to establish and administer educational institutions of their choice. Hence statement 2 is correct

●        The State shall not, in granting aid to educational institutions, discriminate against any educational institution on the ground that it is under the management of a minority, whether based on religion or language.
