Card type semiconductor memory device for storing analog image signals in separate analog memory card units

A card type semiconductor memory device comprising:

• a plurality of analog nonvolatile semiconductor memory chips, where each of said analog nonvolatile semiconductor memory card chips stores a still image formed from a color interleaved analog image signal as mere analog values in units of pixels;
• connection means configured to connect a plurality of signal lines to a host device, said connection means for transferring various signals between said memory chips and said host device, said connection means being arranged on a card-like substrate;
• an analog signal line group coupled to each of said memory chips, said analog signal line group separated from a digital signal line group on said substrate via a separation strip formed from a wide conductive pattern, said analog signal line group concentratedly laid out to converge at said connection means, and said connection means for said analog signal line group separated from said digital signal line group at said connection means;
• and
• terminals in each of said memory chips for said analog signal line group, said terminals being concentrated at a terminal array provided on a predetermined side of said card-like substrate.
