Non-volatile memory e.g. flash memory, device, has multiplexer circuit with program controller generating step control signals such that increment of voltage is varied according to mode of operation

摘要

The device has a word line voltage generator circuit (200) generating a word line voltage to be supplied to a selected row in response to step control signals. A multiplexer circuit (190) has a program controller that generates the step control signals such that an increment of the word line voltage is varied according to a mode of operation. The increment of the voltage during a test mode of operation is larger.
