摘要： Bit line sense amplifier driving control circuits and methods for synchronous DRAMs selectively supply and suspend supply of operating voltages for bit line sense amplifiers. More specifically, a synchronous DRAM includes a memory cell array including at least a first column block and a second column block that are divided according to column address, first bit line sense amplifiers that are configured to sense data that is output from the first column block of the memory cell array, and second bit line sense amplifiers that are configured to sense data that is output from the second column block of the memory cell array. A bit line sense amplifier driving control circuit or method is responsive to a row address select signal, to supply an operating voltage to the first and second bit line sense amplifiers, and is responsive to a column select signal that selects a column address in the first column block, to suspend supplying an operating voltage to the second bit line sense amplifiers.

摘要： A sense amplifier includes a reference signal providing unit and an internal sense amplification unit. The reference signal providing unit provides a reference bit line signal in response to a reference control signal. The internal sense amplification unit receives the reference bit line signal and data signals that correspond to the data. The received signals are provided through bit lines connected to the memory cell array. The internal sense amplification unit senses the received reference bit line signal and the data signals and amplifies the sensed signals. The sense amplifier senses data stored in memory cells connected to dummy bit lines of the outmost memory cell array of a semiconductor memory device such that the memory cells that are not used can be used. Accordingly, the design area and cost of the semiconductor memory device can be reduced.
