Abstract: A memory device and operating method of the memory device are provided. The memory device comprises a memory cell storing data based on a first voltage, a row decoder selecting a wordline of the memory cell based on the first voltage, and a wordline predecoder configured to generate a “predec” signal, which is for generating a wordline voltage to be provided to the row decoder. The wordline predecoder is driven by the first voltage and a second voltage, which is different from the first voltage, receives a row address signal, associated with selecting the wordline, and an internal clock signal associated with adjusting operating timings of elements included in the memory device. The wordline predecoder performs a NAND operation on the row address signal and the internal clock signal, and provides the “predec” signal generated based on a result of the NAND operation to the row decoder.

Abstract: A pseudo dual port memory device in which an operating speed is improved and stability is increased is provided. The pseudo dual port memory device may include a memory cell, a pair of bit lines connected to the memory cell, a write driver, a sense amp, and a column multiplexer which is connected to the bit lines, receives a write multiplexer control signal and a read multiplexer control signal, connects the bit lines to the write driver in response to the write multiplexer control signal, and connects the bit lines to the sense amp in response to the read multiplexer control signal. A precharge control signal generation circuit which is connected to the column multiplexer may generate a precharge control signal on the basis of the read and write multiplexer control signals, and a bit line precharge circuit may precharge the bit lines based on the precharge control signal.
