    摘要: A semiconductor device may comprise a first bit line, a second bit line, a memory cell connected to the first bit line, a bit line sense amplifier circuit and a control circuit. The bit line sense amplifier circuit may be coupled to the memory cell. The bit line sense amplifier circuit may include a first inverter having an input node coupled to the first bit line and an output node coupled to the second bit line, and a second inverter having an input node coupled to the second bit line and an output node coupled to the first bit line. The control circuit may be configured to activate the first inverter without activating the second inverter during a first time period and to activate the first inverter and the second inverter at the same time during a second time period after the first time period.

    摘要: A semiconductor memory device includes a memory cell array including a plurality of memory cell rows; and a data control circuit configured to, sequentially read a first unit of data from N memory cell rows of the plurality of memory cell rows, generate merged test results by comparing bits read from the first units of the N memory cell rows, and output the merged test results, during the test mode of the semiconductor memory device. Therefore, test time for testing the semiconductor memory device may be greatly reduced because a test device may determine pass/fail of the data of the unit of repair unit on one read operation.
