Integrated sensor and memory device for memorizing spatial domain event and corresponding time domain information
DC
First Claim
1. An integrated circuit device for sensing, capturing, memorizing, and preserving spatial and/or time-domain distribution of external events for a long lasting time period without external support, said device comprising:
- a sequence of external events;
an array of cells for sensing and capturing spatial and/or time-domain distribution of selective one or plurality of said extend events;
a source means of charging/loading signal coupled to said cells, said source means produces a sequence of charging/loading signals, wherein each of a plurality of charging/loading signal provide a suitable magnitude to correspond an elapsed time mark with each of said external event;
a memory means for memorizing a present value of said charging/loading signal at a moment of cell activation, which correspond with the time instance when said external event happens, and a means for preserving and maintaining said present value of said charging/loading signal for a long time period without any external support.

Abstract
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.
