MEMORY SYSTEM HAVING NONVOLATILE MEMORY AND BUFFER MEMORY AND DATA READ METHOD THEREOF

摘要

read method of the memory system including a buffer memory and non-volatile memory according to the invention : When a read request comprising an input address is detected that is assigned to the buffer memory ; The address is entered as a search result if it is not assigned to the buffer memory , to determine the size of the requested data is greater than the reference value, the step ; And when the size of the requested data as the determination result is greater than the reference value , and a step of performing a pre-fetch read operation with respect to the non-volatile memory .
