Abstract: The present disclosure is directed to a camera module that includes at least a semiconducting die, an image-sensing circuit, a lens, a lens aperture, and a coating that adheres to an exterior surface of the camera module. The coating is opaque to light and prevents light from accessing the camera other than through the lens aperture. The opaque coating is applied as a fluid and is cured. In one embodiment, a mask material is selectively applied to exterior surfaces of the semiconducting die, electrical interconnect layers, glass layers, the lens body, or the lens aperture.

The internal memory further stores flash data extracted from multiple flash memories. The flash interface portion interacts with the memory devices connected to the controller.

Abstract: A novel method for introducing delays in self timed memories is disclosed. In the proposed method, delays are introduced by introducing a capacitance on the path of signal to be delayed. The capacitances are realized by using idle lying metal layers in the circuit. The signal to be delayed is connected to these idle lying capacitances via programmable switches. The amount of delay introduced depends on the capacitance introduced in the path of signal which in turn depends on state of the switches. The state of the switches is controlled by delay codes provided externally to the delay introducing circuitry. Since, in the proposed method, idle-lying metal capacitances are utilized, the circuit can be implemented using minimum amount of additional hardware. Also delay provided by the proposed circuitry is a function of memory cell spice characteristics and core parasitic capacitances.
