  • Patent number: 7359278
    Abstract: A method for producing an integrated memory module containing a command decoding device that responds to external operation commands to set operating states of the memory module for carrying out operations in accordance with a predetermined specification of the memory module. The command decoding device is formed with a decision memory containing memory locations Mi,j, the storage capacity of which suffices to receive, for an arbitrary specification from a plurality of different specifications, a decision information item specifying whether or how the second operation command of selected pairs of two directly successive operation commands is to be executed. After integration of the command decoding device thus formed, the decision information items demanded in the case of the predetermined specification are written to the memory locations of the decision memory.
