• Pointer Arithmetic and Casting – Manipulating pointers to access specific memory-mapped registers or parse complex data structures.
• Bitwise Operations – Setting, clearing, toggling, and checking specific bits within registers using masks.
• Memory Layout – The precise structure of a compiled binary, including the text, data, bss, stack, and heap segments.
• Advanced concepts (less common) – Writing custom memory allocators, managing memory fragmentation in long-running embedded systems, and implementing lock-free data structures.

Example questions or scenarios:

• "Given a memory-mapped register at address 0x40001000, write a C statement to set bit 5, clear bit 12, and leave all other bits unchanged."
• "Explain how you would detect a stack overflow in an embedded system that does not have a hardware Memory Protection Unit (MPU)."

Computer Organization & Operating Systems

Micron Technology designs memory products that integrate deeply with host operating systems and processors. You must understand how your firmware interacts with these higher-level systems.

Be ready to go over:

• Cache Architectures – L1/L2 cache structures, cache coherency, write-back versus write-through policies, and cache-friendly data structures.
• RTOS Fundamentals – Task scheduling, context switching overhead, priority inversion, and inter-task communication (queues, mailboxes).
• Virtual Memory and MMU – Page tables, TLB hits/misses, and physical-to-virtual address translation.
• Advanced concepts (less common) – Multi-core synchronization, memory barrier instructions, and designing firmware for asymmetric multiprocessing (AMP) systems.

Example questions or scenarios:

• "Describe the step-by-step process of what happens when a CPU experiences a cache miss on a read operation."
• "How would you design a thread-safe circular buffer for a single-producer, single-consumer model without using mutexes?"

Hardware Interfacing & Circuits

Even as a software or firmware engineer, you must be able to read a schematic, understand basic circuit behaviors, and interface with hardware modules.

Be ready to go over:

• Serial Protocols – Physical and logical characteristics of I2C, SPI, UART, and PCIe.
• Basic Circuit Components – Pull-up/pull-down resistors, RC filters, and decoupling capacitors.
• Hardware Debugging – Using logic analyzers, oscilloscopes, and JTAG debuggers to isolate hardware-software boundary issues.
• Advanced concepts (less common) – Signal integrity issues, transmission line effects in high-speed memory buses, and power-delivery network (PDN) noise.

Example questions or scenarios:

• "If you observe a distorted, rounded signal on an I2C clock line, what is the likely physical cause, and how would you fix it?"
• "Explain the handshaking and data transfer mechanism of the SPI protocol. How does it differ from I2C in terms of speed and pin count?"
