NON-VOLATILE SEMICONDUCTOR MEMORY AND DATA READING METHOD THEREOF

摘要

PURPOSE: A non-volatile semiconductor memory and a data reading method thereof are provided to read data at high speed by consecutively transmitting the data to a page buffer from a memory array. CONSTITUTION: A memory array(100) includes a plurality of memory cells. A page buffer(160) stores the data transmitted from selected pages according to address information in the memory array. A data register(130) receives the data from the page buffer and outputs the received data in serial according to a clock signal. The memory array includes a first memory plane and a second memory plane. The data of the selected pages of the first memory plane and the second memory plane is simultaneously transmitted to the page buffer.
