Science

Which phenomenon causes a solid-state drive (SSD) to slow down during prolonged write operations?

A)Increased electron trapping in flash cells
B)Thermal expansion causing controller errors
C)Accumulation of static charge degrading data
D)Increased resistance from oxide layer oxidation

💡 Explanation

During prolonged writes, increased electron injection occurs causing electron trapping in floating gate flash cells because of cell aging effects, leading to reduced program/erase cycle endurance and slower write speeds. Therefore, electron trapping results, rather than thermal expansion, charge accumulation or oxidation which don't directly affect sequential write performance.
