Semiconductor memory fundamentals — “memory configuration” refers to how storage bits are organized internally (e.g., word width, number of addresses, and row/column arrangement). Evaluate this statement.

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:

  • The statement claims that memory configuration refers to the organization of storage bits inside a memory device.
  • Typical configurations are written as words × bits (for example, 64K × 8 or 1M × 16).
  • Row/column addressing and banking are part of array organization.


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:

Identify what “configuration” conveys: words × bits, addressable depth, and width.Relate to signals: number of address pins is determined by the depth; number of data pins by the width.Include physical array aspects: row/column decoding and sense-amp groupings are part of organization.Conclude that the statement correctly captures the meaning of memory configuration.


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:

Incorrect: contradicts industry-standard terminology.“True only for DRAM” or “only for non-volatile”: configuration applies across all memory types.“Meaningful only at module level”: chip-level configuration is fundamental and precedes module assembly.


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
