FAQ
Most frequent questions and answers
Memory comprises a large number of cells. There’s a built-in main memory (sometimes called internal memory), made up of silicon chips (integrated circuits). It can store and retrieve data (computerized information) very quickly, so it’s used to help the computer process whatever it’s currently working on.
In a semiconductor memory chip, each bit of binary data is stored in a tiny circuit called a memory cell, consisting of one to several transistors. The memory cells are laid out in rectangular arrays on the surface of the chip. Consequently, the amount of data stored in each chip is N2M bits.
Silicon is used to make integrated circuit (IC) chips, which are used in computers. An integrated circuit, or IC, is a small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors.
The real “meat” of an IC is a complex layering of semiconductor wafers, copper, and other materials, which interconnect to form transistors, resistors, or other components in a circuit. The tool that cuts and forms the combination of these wafers is called a die.
ICs fail due to several factors. The most frequent causes of IC failure can be classified under manufacturing defects, physical damage to the packaging, harsh operating temperature conditions, and electrostatic discharge (ESD).
Failures due to manufacturing defects
Impurities and contaminants within the bulk silicon, crystal defects, and design issues during IC fabrication all contribute to stability issues in the final chip. Small clearances between the die and the substrate (i.e., die-attach failure) can lower the thermal conductivity of the die.
Failures due to packaging-related damage
Cracks and chips on the packaging of integrated circuits (due to high mechanical stress or process temperatures, etc.) can reduce IC reliability and cause failures during operation. Moisture and cleaning chemicals that get in through cracks can also short out internal parts and cause them to stop working. On top of that, IC packaging can be damaged during shipping or by not being handled properly.
Failures due to operating conditions
High operating and ambient temperatures can cause thermal overstress in ICs. After all, an essential metric for ICs is the junction temperature: ideally, each IC’s junction temperature should not exceed 125 to 150 °C to avoid excessive internal stress. Indeed, using ICs above their maximum-rated voltage and current can cause electrical overstress, which can lead to catastrophic failures.
ICs are far from easy to troubleshoot, particularly when they’re already mounted on a PCB. At least, you can pretty easily tell if an IC is broken and needs to be replaced by using the following methods:
Perform a visual inspection
Again, physical damage to ICs can cause them to malfunction, of course. A visual inspection of the chip can reveal issues like cracks, chipping, and charring that may have resulted from high mechanical impact or overheating.
Check for short-circuiting
One of the best ways to ascertain the condition of an IC is to carry out a short-circuit test. You can test for shorts using a digital multimeter in the following steps:
Set the multimeter to its continuity function
Bridge all the pins on one side of the IC and connect it to one of the multimeter’s test probes.
With the remaining multimeter test probe, check each IC pin for continuity; if more than 50% of the pins have continuity, the IC is likely shorted.
Examine the IC temperature
To check if an IC overheats:
Turn on the device (or supply power to the inputs of the IC for 10 to 15 seconds).
Touch the surface of the IC with the tip of one finger to check its temperature.
Remember that ICs that become very hot after 10 to 15 seconds are likely defective.
Check the IC voltage or signal waveforms
Checking the input and output voltages of ICs to see if they are different from what the manufacturer’s technical document says they should be is probably the most accurate way to find a bad part.
You can use a multimeter to compare the DC input and output voltages of the IC against the values specified in the said technical document. Large disparities between measured and specified voltages indicate a defective component.
Digital ICs are divided into logic ICs (like microprocessors and microcontrollers), memory chips (like MOS memory and floating-gate memory), interface ICs (level shifters, serializers/deserializers, etc.), power management ICs, and programmable devices.
