A semiconductor light-receiving module includes a semiconductor light-receiving element and an incident light direction device. These mechanisms add greatly to the cost, complexity and weight of electric vehicles, reducing their viability. Each destination line card includes a grant generator to generate and send back a grant signal to the source line card in response to the request signal received at the destination line card to authorize the source line card to transmit a data cell to the destination line card. The angle can be selected to effectuate an imaging of a target region of interest at least one of a predetermined depth or range of depths, for example. Programming is done in a vertical page using hot electrons to inject charge onto the floating gates. During normal operation of the chip, the protection transistor is either active for other purposes or is turned off.
