发明名称 Semiconductor device having a mode register and a plurality of voltage generators
摘要 A semiconductor device includes a mode register and a plurality of voltage generators in connection with a plurality of banks. Based on an operation mode set to the mode register, the voltage generators are selectively driven in response to an access to each bank and a CAS latency number defining a delay time between the input timing of an external command and the input/output timing of data of each bank. The number of voltage generators being driven is controlled based on the CAS latency number so that an adequate internal voltage is supplied to the peripheral circuitry, thus adjusting the current consumption without increasing the power consumption.
