Memory map — a “memory map” is an address diagram that shows address ranges and boundaries across a system’s address space. Is this description accurate?

Introduction / Context:
A memory map is foundational documentation for embedded systems, CPUs, and SoCs. It tells firmware developers which address regions correspond to RAM, ROM/Flash, peripherals, and reserved areas. Without a correct memory map, code cannot reliably access devices or storage, and linker configurations would be guesswork.

Given Data / Assumptions:

• The statement frames a memory map as an address-listing diagram showing boundaries of the address space.
• We assume a flat, linear address space typical of many MCUs/MPUs.
• Peripherals may be memory-mapped into specific ranges.

Concept / Approach:
The memory map defines start and end addresses for each region and often annotates access width, privileges, and caching/buffering attributes. It may also indicate boot vectors, interrupt tables, and special-function registers. Maps are used by toolchains (linker scripts) and by board support packages to set up MMU/MPU attributes and to avoid conflicts between code, data, and I/O regions.

Step-by-Step Solution:

Verification / Alternative check:
Review any MCU reference manual: memory maps appear early, listing Flash, SRAM, and peripheral base addresses used by drivers and startup code.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing memory maps with address decoding schematics; ignoring endianness and bus width which are separate concerns.

Final Answer:
