Claim 0:
1. An apparatus comprising:
an array of pixel cells, each pixel cell including:
a photodiode to generate a charge in response to incident light,
a charge sensing unit configured to generate a voltage based on the charge, and
an in-pixel memory configured to store a digital output generated by a quantizer based on quantizing the voltage;

a bus interface;
an off-array frame memory connected to the bus interface and the array of pixel cells, the in-pixel memory of the array of pixel cells being connected to the frame memory via a set of parallel interconnects; and
a frame memory controller configured to:
control the frame memory to receive, via the set of parallel interconnects, the digital outputs from the in-pixel memory of each pixel cell of the array of pixel cells;
store the digital outputs in the frame memory;
fetch the digital outputs from the frame memory; and
transmit the digital outputs to a host device via the bus interface.
