A signature circuit in a semiconductor chip includes a signature program circuit configured to be programmed with signature information and to output a signature signal in response to the signature information; a signature output circuit configured to block the signature signal output by the signature program circuit during operation in a normal mode, and configured to pass the signature signal during operation in a test mode; and a pad-driving transistor directly coupled to the pad, configured to drive the pad during operation in the normal mode in response to an operation command, and configured to drive the pad during operation in the test mode in response to the signature signal output by the signature output circuit. The signature circuit outputs the signature information through a transistor for adjusting impedance to reduce a chip size by omitting an additional logic circuit for the signature circuit.

Method and apparatus for use, e.g., with Synchronous Dynamic Random Access Memory (SDRAM) circuits are disclosed. In one described embodiment, three metal layers are deposited and patterned in turn overlying a memory array portion of an SDRAM. Relatively wide power conductors are routed on a third metal layer, allowing power conductors to be reduced in size, or in some cases eliminated, on first and second metal layers. The relatively wide power conductors thus can provide a more stable power supply to the memory array, and also free some space on first and/or second metal for routing of additional and/or more widely spaced signal conductors. Other embodiments are described and claimed.

An address buffer circuit for a semiconductor memory device wherein an address buffer is enabled (to output an internal address signal) in response to a first level of a control signal and, but is disabled in response to a second level of the control signal. An address buffer control unit generates the control signal at the second level in ‘no operation’ state (NOP command) in which the semiconductor memory device does not perform data accessing operations and generates the control signal at the first level while the semiconductor memory device performs data accessing operations, thereby reducing or minimizing the output of an internal address buffered and output by the address buffer at and thus reducing power consumption during no-operation states of the semiconductor memory device.

A method of verifying a layout of a vertical memory device includes classifying a plurality of channel holes included in the layout of the vertical memory device into a plurality of types based on at least one of a distance between each channel hole and an isolation region adjacent thereto, shapes of the plurality of channel holes in the layout, and coordinates of the plurality of channel holes in the layout. Types of channel holes connected to each of a plurality of bit lines included in the layout are identified, and a determination is made whether loads of the plurality of bit lines are equalized, based on the identified types of the channel holes for each bit line.

A polarizing panel includes a first substrate, a second substrate and an interposed first liquid crystal layer. The first substrate includes a plurality of spaced apart and segment electrodes and segments of a first light-blocking member disposed within interval areas between the segment electrodes. The second substrate faces the first substrate to include a common electrode facing the segment electrodes. The first liquid crystal layer is able to selectively apply a first polarizing effect to light rays passing therethrough when in a corresponding first state and to apply a different second polarizing effect to passing through light rays when in a corresponding second state, where the first and second states can be selectively chosen by voltages applied to the segment electrodes. The light-blocking member can reduce image crosstalk lights from being emitted from the interval areas between the segment electrodes, so that a crosstalk component of a formed 3D image may be prevented or reduced due to light-blocking effects.
