Abstract
A method for extending period of data retention of a flash memory device and a device for the same are disclosed. In the present invention, the temperature of the flash memory device is detected by a temperature sensor. According to the temperature and P/E cycles of the flash memory device, a safe period is obtained for the data retention of the flash memory device. By refreshing each block of the flash memory device during the safe period, the data retention period is refreshed, and the data stored in the flash memory device can be prevented from bit error caused by exceeding data retention period or read disturb.
