NON-VOLATILE MEMORY SYSTEM INCLUDING A PLURALITY OF MEMORY CELL ARRAYS HAVING DIFFERENT READ STAND-BY TIME AND DATA READ METHOD OF THE NON-VOLATILE MEMORY SYSTEM

摘要

A non-volatile memory system comprising a plurality of memory cell arrays having different read stand-by time and a data read method of the non-volatile memory system are provided to start to read data from a memory cell array with short read stand-by time after receiving a read command at the same time and starting to prepare read operation at the same time. A single-level cell array(310) includes a number of single-level cells. A multi-level cell array(320) includes a number of multi-level cells. The multi-level cell(MLC) and the single-level cell(SLC) receive a read command at the same time, and start to prepare read operation at the same time. The single-level cell array starts to read data earlier than the multi-level cell array.
