    • An integrated circuit memory device includes a DQM input buffer controller that enables the DQM buffer to process the DQM mask signal during a row active period of a read operation and a write operation of an integrated circuit memory device, and during a latency period of the read operation and the write operation, and that disables the DQM buffer otherwise during the read operation and the write operation. Thus, the DQM buffer is enabled to process the DQM mask signal during those portions of the read and write operations in which the external DQM mask signal is received and the DQM buffer is otherwise disabled during the read and write operations. The controller can also disable the DQM buffer during a refresh operation of the memory device and a power-down operation of the memory device. Accordingly, reduced current consumption in the DQM buffers may be obtained by only enabling the DQM input buffers when a DQM mask signal is expected during the read and write operations of the memory device.

    • Voltage boosting circuits include backup voltage boosting circuits which are enabled during high current loading conditions when voltage sags in the potential of a boosted signal line(s) are encountered, and which provide independent level detection capability to bypass main voltage level detectors when relatively severe voltage sags are anticipated. In particular, voltage boosting circuits are provided which contain a main voltage boosting circuit and a backup voltage boosting circuit therein. The main voltage boosting circuit is typically powered at a first reference potential (e.g., Vcc) and preferably contains a main level detector, a built-in oscillator and a main pump coupled in series to drive a signal line (e.g., Vpp) to a boosted reference potential which is greater than the first reference potential, if a potential of the signal line drops below a second reference potential. To supplement the voltage boosting capability of the main pump, a backup voltage boosting circuit is provided containing an independent voltage level detector and at least one backup pump coupled in series therewith, to drive the signal line to the boosted reference potential, if the potential of the signal line drops below a third reference potential which may be greater than or equal to the second reference potential. Accordingly, the occurrence of relatively small voltage sags in the potential of the boosted signal line (e.g., Vpp) can trigger the backup pump during anticipated high current loading conditions, while the occurrence of larger voltage sags in the potential can trigger the main pump to assist the backup pump.

    • An auto precharge control signal generating circuit includes an output enable circuit that is reset in response to a precharge operation and generates an output enable signal by latching an auto precharge command signal. A delay circuit also is provided which generates a 1 clock delay signal by delaying an active period of a column bank address signal by 1 clock, and generates a 1 clock delay signal having an active period including a non-active period sufficiently between a previous column bank address signal and a present column bank address signal in case that the burst length is 1. A combining circuit generates an auto precharge control signal by combining the column bank address signal and the 1 clock delay signal in response to the output enable signal, in order to perform the auto precharge operation after delaying 2 clock from the last data input in response to a continued auto precharge burst write command. Therefore, when the burst length is 1 in case that the time from the last data input to the auto precharge is 2 clock cycles in burst write, the present invention prevents the generation of unnecessary auto precharge control signal resulting from the crossing of the 1 clock delay signal and the column bank address signal in the middle of continuous burst write operation.
