摘要

There are provided a universal asynchronous receiver/transmitter (UART) unit, and a memory controller and a memory system, which have the UART unit. A UART unit includes: a WORD table to store text information and a plurality of word codes corresponding to the text information, and to output a first word code corresponding to first text information when the first text information is received by the WORD table, wherein the text information includes a plurality of words, and the first text information includes a first word among the plurality of words; a UART controller to output the first text information to the WORD table by extracting the first word from output information, and to output an output code based on the output information and the first word code when the first word code is received from the WORD table; and a UART to output debugging information based on the output code.
