US 8,300,495 B2 · Block control command generation circuit

Abstract

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.

A block control command generation circuit comprising:

first and second latch units configured to store initial values at different levels in response to initialization signals;
an input selection unit configured to selectively transmit a first block control signal to the first latch unit in response to an input enable signal;
a pull-down driving unit configured to selectively pull-down drive an input node of the second latch unit in response to a second block control signal and the input enable signal;
and
an output selection unit configured to output signals stored in the first and second latch units as first and second block control command signals, respectively, in response to an output enable signal.
