A vertical memory device includes a substrate, a plurality of channels extending in a first direction substantially vertical to a top surface of the substrate, a plurality of gate lines surrounding a predetermined number of channels from among the channels, a plurality of common wirings electrically connected to the gate lines, and a plurality of signal wirings electrically connected to the gate lines via the common wirings. The gate lines are arranged and spaced apart from one another along the first direction. Each common wiring is electrically connected to a corresponding gate line at a same level of the corresponding gate line via a corresponding contact.

In a method of operating a nonvolatile memory device, a first sub-block to be erased is selected in a first memory block including the first sub-block and a second sub-block adjacent to the first sub-block, in response to a erase command and an address. The first sub-block includes memory cells connected to a plurality of word-lines including at least one boundary word-line adjacent to the second sub-block and internal word-lines other than the at least one boundary word-line. An erase voltage is applied to a substrate in which the first memory block is formed. Based on a voltage level of the erase voltage applied to the substrate, applying, a first erase bias condition to the at least one boundary word-line and a second erase bias condition different from the first erase bias condition to the internal word-lines during an erase operation being performed on the first sub-block.

A method for controlling operations of an air-conditioner includes: a step in which when an operation load of an air-conditioner increases, if an outputted compressing capacity of the air-conditioner is smaller than a compressing capacity corresponding to the operation load and an operation frequency of the first compressor is a maximum frequency of the first compressor, a second compressor is operated; and a step in which when the operation load is reduced, if the outputted compressing capacity of the air-conditioner is greater than the compressing capacity corresponding to the operation load and the operation frequency of the first compressor is a minimum frequency of the first compressor, the second compressor is stopped.

An outdoor unit for an air conditioner having a reinforcing structure is disclosed. The outdoor unit comprises a base plate arranged at a bottom portion of a body of the outdoor unit; an upper plate arranged at an upper portion of a body of the outdoor unit; a plurality of support members connected between the base plate and the upper plate and arranged towards a circumference of the body with predetermined intervals; and a reinforcing member arranged between the support members for supporting the body of the outdoor unit, wherein the reinforcing member includes an upper reinforcing rod connected to both sides of the upper plate and prolonged to a lower direction; a lower reinforcing rod connected to both sides of the base plate and prolonged to an upper direction; and a connection reinforcing rod connected between the upper and lower reinforcing rods, thereby simplifying a construction of the reinforcing member which increases an intensity of the body of the outdoor unit and reduces a vibration. According to this, fabricating processes are simplified and a fabrication cost is minimized.
