Abstract
A memory device and a method for protecting the same are provided. The memory device includes a controller configured to refresh one of word lines during a first refresh cycle in response to a refresh signal, a number trimmer configured to generate a modified first number according to a first number generated by a random number generator, wherein the modified first number is less than a first predetermined number. The memory device further includes a counter configured to receive the modified first number as an initial value, and to be turned on in response to the refresh signal. The controller is configured to obtain an address of a first word line being accessed when the counter counts to zero, and refresh a second word line during a second refresh cycle, wherein an address of the second word line is adjacent to the address of the first word line.
