SRAM and flash memory

Under which condition does the data retention of flash memory tend to degrade?

  1. AWhen stored at low temperature
  2. BWhen stored in a dark place
  3. CWhen stored at high temperature
Show answer and explanation

Answer: C. When stored at high temperature

Electrons stored in flash memory escape through the insulator more easily at higher temperatures, so storage at high temperature shortens data retention. Retention also degrades when the oxide has been worn by repeated rewriting.
