Generally speaking, the chip will not shrink for a long time, but some electrons inside the chip will change after a long time, resulting in increased power consumption. The aging process is strictly tested at the factory, and the purpose of the aging process is to reduce the failure rate of the chip.

The chip is used for a long time to a certain extent, although the manufacturer's pre-design frequency will not decrease, it is followed by various failures, which is reflected in the error rate increase, although the chip itself also has error correction technology, but there are some problems that the error correction technology can not help.
