A capacitor-less memory cell, memory device, system and process of forming the capacitor-less memory cell includes forming the memory cell in an active area of a substantially physically isolated portion of the bulk semiconductor substrate. The first command is configured to direct the player to play a first content on the article if the first register is set to the default value and to direct the player to play a second content on the article if the first register is set to the non-default value. The training yields a spectral data-activity relationship that may be used to predict the endpoint value of a molecule from its spectral data alone. The method allows for high accuracy to be achieved for determination of the modulation sequence of the downlink synchronization codes.
