Abstract

A FIFO with ECC function is provided. A check code will be generated by computing an input data word in an ECC encoder unit before the input data word is wrote into FIFO. Then, the check code will be stored in FIFO with the input data word. The error bits of the input data word will be checked and corrected by using the check code stored with it while the input data word is read from FIFO, so that the input data is not affected with noise and the signal integrity is enhanced.
