Abstract
A semiconductor device includes: memory regions that include non-volatile memory cells; disabling information memory units that correspond to the memory regions, each of the disabling information memory units storing first program disabling information indicating whether programming is to be disabled or enabled in each corresponding memory region; a program disabling information selection circuit that outputs second program disabling information for disabling programming in a corresponding memory region, regardless of the first program disabling information, when programming is disabled collectively in the memory regions in accordance with collective program disabling information indicating whether programming is to be disabled collectively in the memory regions, the program disabling information selection circuit outputting the first program disabling information as the second program disabling information when programming is not collectively disabled; and a program control circuit that disables or enables programming in the corresponding memory region in accordance with the second program disabling information.
