Abstract
A high voltage generating circuit may include a pulse signal generator, a counter, a plurality of transmitters, and/or a plurality of pumpers. The pulse signal generator may be configured to be enabled in response to a refresh command signal to output a pulse signal. The counter may be configured to count the pulse signal and sequentially output a plurality of selection signals. The plurality of transmitters may be configured to be sequentially enabled in response to individual selection signals of the plurality of selection signals to transmit the pulse signal. The plurality of pumpers may correspond to the plurality of transmitters. Each of the plurality of pumpers may be configured to collectively generate a high voltage based on the transmitted pulse signal from a corresponding transmitter of the plurality of transmitters.
