← ScienceWhich 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.
