Abstract
A single-wire two-way communication circuit includes two chips and a data transmission line coupled between the two chips. Each chip includes a random access memory, a data control module, a data line control module, and a data line monitoring module. The random access memory stores data. The data control module obtains data of a first address from the random access memory and stores data of a second address received from the other chip into a second address of the random access memory. The data line control module sends the obtained data of the first address to the other chip through the data transmission line to perform a write operation. The data line monitoring module receives the data of the second address sent by the other chip through the data transmission line to perform a read operation.
