Analog storage for a cmos array

Abstract From the Canadian patent

The image sensor comprises an analog memory array integrated on a die with a CMOS sensor array and coupled to the sensor array for receiving light intensity, signals from the sensor array. The sensor array may comprise light sensitive pixels, arranged in rows and columns equal in number or greater than the number of memory, cells in the memory array which are also arranged in rows and columns. The memory, cells may be grouped into one or more distinct memory arrays. The image sensor operates in a rolling shutter mode which closely approximates electronic frame capture since the transfer process can be made sufficiently fast. This CMOS image, sensor is particularly advantageous since it …
