The repeated toggling of a row's wordline can disturb nearby cells and make them lose charge, if a cell loses too much charge before it is restored, it experiences a disturbance error. The following code is used to disturb the cells:

code1a:
mov (X), %eax
mov (Y), %ebx
clflush (X) // See Vol 3 11.5.5
clflush (Y)
mfence // Not used in the Google's article.
jmp code1a

In this structure, when the access transistor is turned on by applying a voltage on the gate of the access transistor, a voltage representing the data value is placed onto the bitline and charges the storage capacitor. The storage capacitor then retains the stored charge after the access transistor is turned off and the voltage on the wordline is removed. However, the electrical charge stored in the storage capacitor will gradually leak away with the passage of time. To ensure data integrity, the stored data value in the DRAM cell must be periodically read out and written back by the DRAM device in a process known as refresh.
