Circuit and method for generating mode register set code

摘要

A circuit that includes a data input circuit for outputting data in response to a first signal, a logic circuit for generating a second signal in response to the first signal, a latch circuit for latching the data in response to the second signal, and a decoder for decoding an output signal of the latch circuit and for generating a code. A method includes outputting a mode register set (MRS) code based upon data received by a circuit implemented in a semiconductor device, where the data is unrelated to register data.
