  Calorimeters with silicon detectors have many unique features and are
proposed for several world-leading experiments. We describe the R&D program of
the large scale detector element with up to 12 000 readout channels for the
International Large Detector (ILD) at the future e+e- ILC collider. The program
is focused on the readout front-end electronics embedded inside the
calorimeter. The first part with 2 000 channels and two small silicon sensors
has already been constructed, the full prototype is planned for the beginning
of 2018.
