The present invention relates to a CMOS image sensor having a wide dynamic range, which permits favorable imaging even in cases where a bright portion and a dark portion exist simultaneously. The dynamic range can be widened by preventing the saturation of optical charge at a high illuminance by removing low illuminance signals due to long-time accumulation, intermediate illuminance signals due to short-time accumulation, and high illuminance signals due to ultra-short time accumulation from pixel portions of the image sensor. Further, adaptive control of the dynamic range can also be performed by dynamically changing the wide dynamic range imaging conditions that comprise a combination of different accumulation times of each of a plurality of short time accumulation signals.

Read-assist circuits for memory bit cells employing a P-type Field-Effect Transistor (PFET) read port(s) are disclosed. Related memory systems and methods are also disclosed. It has been observed that as node technology is scaled down in size, PFET drive current (i.e., drive strength) exceeds N-type FET (NFET) drive current for like-dimensioned FETs. In this regard, in one aspect, it is desired to provide memory bit cells having PFET read ports, as opposed to NFET read ports, to increase memory read times to the memory bit cells, and thus improve memory read performance. To mitigate or avoid a read disturb condition that could otherwise occur when reading the memory bit cell, read-assist circuits are provided for memory bit cells having PFET read ports.
