MEMORY CONTROL CIRCUIT, MEMORY SYSTEM HAVING THE SAME AND OPERATING METHOD THEREOF

摘要

The present invention relates to a memory control circuit and a memory system including the memory control circuit. The memory control circuit includes: a buffer which stores the input data received from an external source; a random control circuit which receives a part of the input data as seed data and generates to a data enable signal, high, in proportion to the size of the seed data; a random code generation circuit which generates a random code in response to the seed data and the data enable signal; and a data conversion circuit which runs a logical operation with the seed data and the random code to output random data.
