An integrated sensor and memory device for sensing, capturing, and memorizing spatial and/or time domain distribution of events, comprises a sequence of events; an array of cells for sensing and capturing spatial and/or time domain distribution of each event; source for charging/loading signal coupled to each cell, wherein each charging/loading signal provides a suitable magnitude to correspond with an elapsed time mark of each event; and memory cell integrated within each cell, that memorize current value of charging/loading signal at the moment of cell activation, which correspond with the time instance when an event happens.
