A full-stress testable memory device having an open bit line architecture and a method of testing the memory device. The memory device of the invention includes dummy bit lines, and a voltage controller connected to the dummy bit lines. The voltage controller alternately provides a first variable control voltage and a second variable control voltage to the dummy bit lines during a test mode. In accordance with a method of testing the memory device, a fixed voltage is provided to the dummy bit lines of the edge sub-arrays during a normal operation mode. However, during a test mode, the fixed voltage being applied to the dummy bit line is replaced with a supply voltage and/or a ground voltage, so that all of the sub-arrays can be equally tested.

A high vacuum apparatus for fabricating a semiconductor device includes a reactive chamber provided with an inlet and an outlet for a reactive gas, a suscepter installed in the reactive chamber for mounting the semiconductor thereon and a vacuum pump connected with the outlet to make the inside of the reactive chamber to put in a high vacuum state, wherein a gas injector of the reactive gas inlet is directed downward of the semiconductor device so that the initial gas flowing of the reactive gas injected from the reactive gas inlet does not directly pass the upper portion of the semiconductor substrate mounted on the suscepter. Since the reactive gas is prevented from cooling and condensing at the upper surface of the semiconductor substrate, defective proportion of the semiconductor device can be remarkably reduced. In addition, the gas outlet is installed at the portion where the reactive gas is satisfactorily cooled and condensed and the vacuum pump is connected with the gas outlet, so that the cooled and condensed contaminant generating source is quickly removed, and thus the defective proportion of the semiconductor device can be considerably reduced.

Disclosed is a burst-type random access memory device with a double data rate scheme, in which at least two data is inputted/outputted to/from the memory device during a clock cycle. In the burst-type random access memory device, a first address generator is further provided, which generates a sequence of addresses in response to an externally applied initial address, wherein the first addresses correspond to a first half period of the clock cycle during a burst mode of operation, respectively. And, in the memory device, a second address generator is furthermore provided, which receives the addresses from the first address generator and generates a sequence of addresses in accordance with burst information signals each indicative of a burst length and a type of the burst mode of operation, wherein the second addresses correspond to a second half period of the clock cycle during the burst mode of operation, respectively. According to the burst-type random access memory device, the second address generator is implemented such that the address for the second half period of a clock cycle is automatically generated in accordance with the burst length and mode. With the configuration, the access of the burst-type random access memory device with the DDR scheme can be speeded up.
