MEMORY SYSTEM AND READING METHOD THEREOF

摘要

According to the present invention, a method for reading a non-volatile memory device comprise steps of receiving input of a read order; analyzing whether an operation mode is a consecutive read mode or not; authorizing pre-pulse having a pre-determined level during a pre-determined period of time in which non-selective string select lines are determined among the string select lines; and reading data of a memory cell of a selected string select line among multiple string select lines by authorizing read voltage to the selected string select line among the string select lines.
