Patent ID: 11901028
Assignee: CHANGXIN MEMORY TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 12:
13. A storage apparatus comprising a data transmission circuit, wherein the storage apparatus is configured to store and transmit data of a read operation or a write operation;
wherein the data transmission circuit comprises:
a check circuit configured to generate check code data according to first data on a first data line, and combine the first data and the check code data into second data;
a comparison circuit electrically connected to the first data line, the check circuit and a second data line, the comparison circuit being configured to receive the second data and third data on the second data line, and compare the second data with the third data to output a comparison result indicating whether number of different bits between the second data and the third data exceeds a preset threshold, wherein the second data and the third data have a same preset bit width; and
a data conversion circuit electrically connected to the check circuit, the comparison circuit and the second data line, the data conversion circuit being configured to invert the second data and transmit an inverted second data to the second data line when the comparison result is indicative of exceeding the preset threshold; and the data conversion circuit being further configured to transmit the second data to the second data line when the comparison result is indicative of not exceeding the preset threshold.
