Today we continue our series on learning about the semiconductor industry. We are using the book, Understanding Semiconductors: A Technical Guide For Non-Technical People” by Corey Richard to guide our studies. This is a great book about semiconductors and I highly recommend it. We will go through some of the terms in Chapter 6 today.
If you are unfamiliar with the semiconductor industry, I suggest starting from the first post in this series.
Disclaimer: The videos below do not belong to us. The creators are mentioned in each video.
Analog Signal: When data is transferred by a continuous wave signal.
Digital Signal: When data is transferred using 0's and 1's (binary language).
Frequency: The number of times an analog signal wave travels up and down within a period of time.
Hertz: The number of times a signal wave travels up and down within 1 second
Microcontroller: A mini computer that can only perform 1 task.
CPU Register: Memory that is located on the CPU and provides quick access to data. Registers are faster than Cache but stores less data.
CPU Cache: Memory that provides data quickly to CPU. Cache has 3 levels. Level 1 provides data faster than Level 2 and Level 2 is faster than Level 3.
Static Random Access Memory (SRAM): Memory that stores data temporarily. SRAM is faster than Dynamic Random Access Memory (DRAM) and consumes less power.
Primary Memory: Memory that is connected to the CPU and is faster than the secondary memory. RAM is considered primary memory.
Secondary Memory: Memory that stores data permanently. Secondary memory does not have direct access to the CPU. It communicates with the CPU through the primary memory. Secondary memory is cheaper than primary memory. Hard Disk Drives are considered secondary memory.
NAND Flash Memory: Memory that stores data permanently.
High Bandwidth Memory (HBM): Structure where memory chips are stacked on top of each other instead of side by side. Compared to other memory chips, HBM is faster, consumes less power, and takes up less space.
Photonic Integrated Circuits: The use of light to transmit data.
Power Management Integrated Circuits (PMIC): Chips that regulate the amount of power being distributed to different parts of an electronic device.
CONCLUSION
Next week we will review Chapter 7 of the Semiconductor Book.
Stay strong, stay blessed, and God willing, I will see you next week.
Love the Lord, all you godly ones! For the Lord protects those who are loyal to him, but he harshly punishes the arrogant. So be strong and courageous, all you who put your hope in the Lord!
Psalms 31:23-24 NLT
