IMAGE SENSOR USING DYNAMIC RANDOM ACCESS MEMORY

A new and improved solid-state image sensor uses a dynamic random access memory as the light sensitive element. The dynamic random access memory is mounted in a semiconductor package having a transparent lid, and one or more lenses focuses the light image onto the dynamic random access memory. A recording device or a display unit is provided. The new and improved solid-state sensor is particularly useful in low-cost applications, such as robots and toys.
