Abstract
An event-driven sensor including: a pixel array; a column readout circuit coupled to column output lines of the pixel array, the column readout circuit including a plurality of column register cells; and a row readout circuit including a readout memory having a storage location corresponding to each pixel of the pixel array, the readout memory having sets of one or more row lines for writing to rows of memory locations of the readout memory, wherein each row output line of the pixel array is coupled, via a corresponding row line control circuit, to a corresponding one of the sets of one or more row lines of the readout memory.
