A verifying method for an error checking and correcting (ECC) circuit of a static random-access memory (SRAM) is provided. The SRAM comprises a storage unit, an ECC circuit and a checking circuit. The ECC circuit receives an original data and an output first data. The checking circuit obtains a second data according to an error-injecting mask. The checking circuit performs a bit operation on the first data and the second data to obtain a third data. The checking circuit writes the third data into a test target area of the storage unit and the written data as a fourth data. The checking circuit reads the fourth data from the test target area. The ECC circuit obtains a fifth data and an error message according to the fourth data. The checking circuit obtains the bit error detection result according to the error message and the second data.

Verifying method for ECC circuit of SRAM

An Ethernet connection method and an Ethernet device thereof are provided. The Ethernet connection method and the Ethernet device can transmit data with Error Correction Code (ECC) even with only one twisted pair or two twisted pairs when the Ethernet wire cannot transmit with the full four twisted pairs.
