    摘要: A block control command generation circuit includes first and second latch units, an input selection unit, a pull-down driving unit, and an output selection unit. The first and second latch units store initial values at different levels in response to initialization signals. The input selection unit selectively transmits a first block control signal to the first latch unit in response to an input enable signal. The pull-down driving unit selectively pull-down drives an input node of the second latch unit in response to a second block control signal and the input enable signal. The output selection unit outputs signals, which are stored in the first and second latch units, as first and second block control command signals in response to an output enable signal, respectively.

When a one time programmable (OTP) device is programmed, the semiconductor memory device prohibits lock-status information pre-stored in an OTP lock register from being changed to an unlock status, such that it increases the stability of data stored in an OTP area. The semiconductor memory device includes an OTP device configured to determine whether or not data is changed according to a lock/unlock status when a program command is received, and an OTP controller configured to prohibit the lock status from being changed to the unlock status.
