摘要： An internal voltage generator includes a comparison unit, a driving circuit and a bias unit. The comparison unit compares a reference voltage and an internal voltage and is configured to output a comparison voltage, which is based on a difference between the reference voltage and the internal voltage. The driving circuit receives the comparison voltage and an external power supply voltage and is configured to output the internal voltage to an output node in response to the comparison voltage. The bias unit receives the internal voltage and is configured to adaptively adjust a bias current that flows through the bias unit to drive the comparison unit, in consideration of a level of the internal voltage.

摘要： DC balance encoded data is transmitted by transmitting a preamble of dummy data that is configured to provide an intermediate number of bits of a given logic value that is at least one bit of the given logic value but less than a maximum number of bits of the given logic value in the DC balance encoded data, to thereby reduce the simultaneous switching noise that is caused by transmission of a first word of DC balance encoded data. The preamble may contain one or more words of fixed and/or variable dummy data.

摘要： Semiconductor devices, a system including said semiconductor devices and methods thereof are provided. An example semiconductor device may receive data scheduled for transmission, scramble an order of bits within the received data, the scrambled order arranged in accordance with a given pseudo-random sequence. The received data may be balanced such that a difference between a first number of the bits within the received data equal to a first logic level and a second number of bits within the received data equal to a second logic level is below a threshold. The balanced and scrambled received data may then be transmitted. The example semiconductor device may perform the scrambling and balancing operations in any order. Likewise, on a receiving end, another semiconductor device may decode the original data by unscrambling and unbalancing the transmitted data. The unscrambling and unbalancing operations may be performed in an order based upon the order in which the transmitted data is scrambled and balanced.
