Why “flash” memory is called flash: Flash memories are so named because of their rapid ________ times.

Introduction / Context:
Flash memory evolved from EEPROM technology with improved block erase mechanisms. The term “flash” reflects that large blocks can be erased quickly, almost “in a flash,” enabling practical reprogramming compared with byte-erasable EEPROMs.

Given Data / Assumptions:

• Flash supports block (sector/page) erase operations.
• Write (program) times per page/word are designed for practical firmware updates.
• Random reads are also fast, but erase is the historically notable improvement.

Concept / Approach:
Flash excels at rapid block erasure followed by programming, making it useful for code storage that needs occasional in-field updates. While read latency is important, what differentiates flash from older EEPROM is the efficient erase/program cycle for larger regions rather than slow, byte-at-a-time erasure.

Step-by-Step Solution:

Verification / Alternative check:
Device datasheets list sector erase times and page program times as key specs, emphasizing update speed compared to legacy EEPROM.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming “flash” refers primarily to read performance; the key differentiator is erasability/programming of large blocks.

Final Answer:
erase and write
