Which outcome is caused by increased electron tunneling in a flash memory cell array?

A)Reduced data retention time
B)Increased programming speed
C)Lower power consumption during read
D)Improved endurance cycle limit

💡 Explanation

When electron tunneling increases, trapped electrons leak out of the floating gate due to the quantum mechanical effect of electrons passing through an energy barrier, causing charge loss during storage, leading to reduced data retention. Therefore, data retention time declines, rather than faster programming, lower power, or higher endurance which require different optimization strategies.
