Abstract
In a card type semiconductor memory device, at least one memory chip for storing a still image and a connector having a number of signal lines for transferring various signals between the memory chip and a host device are mounted on a card-like substrate. The memory chip includes a memory section and a signal processing section. The memory section includes analog nonvolatile semiconductor memories for sequentially storing, as analog values, color interleaved analog image signals having analog luminance information of predetermined colors in units of pixels in synchronism with a predetermined clock signal. The signal processing section calculates, as analog values, the luminance information at a plurality of pixel positions, which are read out from the memory section, to convert the luminance information into color image data having analog luminance information of the respective colors in units of pixels and outputs the color image data.
