Title: MAGNETORESISTIVE MEMORY APPARATUS CAPABLE OF RECOGNIZING STATE CHANGE DURING WRITING OPERATION, AND READING AND WRITING OPERATION METHOD THEREFOR
Abstract:
Disclosed are a transmitter which requires only a low cost and a small area and can eliminate switching noise, and a data transmission method therefor. The transmitter comprises: an encoder for converting two-level input data (1 and 0) into three-level data (+1, 0, and -1); and an output unit for outputting the data converted by the encoder. Here, the encoder adds one bit to the input data so that the number of bits corresponding to logic "1" is adjusted to an even number. Also, "+1" and "-1" corresponding to the logic "1" are alternately arranged, and a particular correlation is established between currents or voltages corresponding to at least two levels among the levels "+1", "0", and "-1" so as to allow a current flowing through a power line or a ground line to be constant regardless of the input data.
