Difficulty: Easy
Correct Answer: Correct
Explanation:
Introduction / Context:
When discussing semiconductor memories, engineers frequently talk about a device’s “configuration.” This term does not describe packaging or speed grade; instead, it captures how the storage bits are structured inside the memory array, including how many addresses exist and how wide each data word is. Understanding configuration aids in correct interfacing with microprocessors, controllers, and buses.
Given Data / Assumptions:
Concept / Approach:
Configuration expresses the logical mapping from addresses to stored bits. For a device labeled 64K × 8, there are 65,536 addresses (words), each returning 8 data bits. Internally, the array is commonly arranged in rows and columns with decoders, sense amplifiers, and I/O gating to present the selected bits on the data bus. Configuration impacts how many address lines (A0…An) and data lines (D0…Dm) the system must route, and it dictates byte/word organization, banking, and interleaving strategies.
Step-by-Step Solution:
Verification / Alternative check:
Check datasheets for SRAM/DRAM/Flash devices. The first line of the features table typically lists configuration (e.g., “512K × 8”). The pin description aligns exactly with this organization via address and data pin counts.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing “configuration” with timing parameters; conflating package pinout with logical organization; ignoring endianness (a system-level convention) versus device configuration (a chip attribute).
Final Answer:
Correct
