Non-volatile memory device capable of changing increment of program voltage according to mode of operation

摘要

A non-volatile memory device includes a word line voltage generator circuit for generating a word line voltage to be supplied to a selected row in response to step control signals and a program controller for sequentially activating the step control signals during a program cycle. During the program cycle, the word line voltage generator circuit controls the increment of the word line voltage differently according to the mode of operation, namely, a test mode or a normal mode. Thus test time can be shortened.
