Abstract: Readout circuitry to readout an array of image sensor pixels includes readout units that include a plurality of analog-to-digital converters (“ADCs”), a plurality of blocks of Static Random-Access Memory (“SRAM”), and a plurality of blocks of Dynamic Random-Access Memory (“DRAM”). The plurality ADCs is coupled to readout analog image signals two-dimensional blocks of the array of image sensor pixels. The plurality of blocks of SRAM is coupled to receive digital image signals from the ADCs. The digital image signals are representative of the analog image signal readout from the two-dimensional block of pixels. The plurality of blocks of DRAM is coupled to the blocks of SRAM. Each block of SRAM is coupled to sequentially output the digital image signals to each of the blocks of DRAM. Each of the readout units are coupled to output the digital image signals as a plurality of Input/Output (“IO”) signals.
