Difficulty: Easy
Correct Answer: Appropriate (Correct)
Explanation:
Introduction / Context:
“Storage density” is a comparative metric used across memory technologies—DRAM, SRAM, Flash, EEPROM—to indicate how much information can be stored within a given device or physical footprint. It informs cost per bit, integration level, and suitability for applications ranging from caches to mass storage.
Given Data / Assumptions:
Concept / Approach:
Storage density can be expressed as capacity per chip (e.g., 8 Gbit per die), capacity per unit area (bits/mm^2), or per package. Higher density generally correlates with more aggressive lithography, multi-level cell schemes (in Flash), or denser cell topologies (in DRAM). Designers weigh density against speed, endurance, power, and cost when selecting devices.
Step-by-Step Solution:
Verification / Alternative check:
Review vendor datasheets and process technology briefs; they consistently emphasize density alongside timing and power as key differentiators.
Why Other Options Are Wrong:
Common Pitfalls:
Equating density with speed; they are independent metrics. Also, assuming more density always means better—endurance, latency, and power can trade off.
