Some embodiments of the invention relate to an embedded processing system. The system includes a memory unit to store a plurality of operating instructions and a processing unit coupled to the memory unit. The processing unit can execute logical operations corresponding to respective operating instructions. An input/output (I/O) interface receives a first time-varying waveform and provides an I/O signal that is based on the first time-varying waveform. A comparison unit coupled to the processing unit and adapted to selectively assert an error signal based on whether the I/O signal has a predetermined relationship with a reference signal, wherein the predetermined relationship holds true during normal operation but fails to hold true when an unexpected event occurs and causes an unexpected change at least one of the I/O signal and reference signal.

Methods and systems for measuring I/O signals

A NAND-type flash memory device is described. In some embodiments, the memory device includes NAND-type flash memory cells, and a synchronous NAND interface. The synchronous NAND interface includes a standard NAND flash interface pin arrangement and a clock (CLK) pin. The synchronous NAND interface is configured to interface with a NOR-compatible memory interface.

Interface for NAND-type flash memory

An embodiment of the invention describes a method for enumeration. The method includes assigning a second number to a device of a plurality of devices, wherein each device of the plurality of devices has a different unique first number. The method includes comparing at least portions of the first numbers and assigning a second number to one of the plurality of devices depending on the result of the comparison.

Method and device for enumeration

A non-volatile memory device is proposed. The non-volatile memory device includes a flash memory and means for executing external commands, the external commands including a first subset of commands for accessing the flash memory directly; the memory device further includes a programmable logic unit and means for storing program code for the logic unit, the external commands including a second subset of at least one command for causing the logic unit to process information stored in at least one portion of the flash memory under the control of the program code.

Non-volatile memory device

The invention relates to a process for manufacturing a light sensor device in a standard CMOS process, including at least the following phases: implanting active areas on a semiconductor substrate to obtain at least a first, a second and a third integrated region of corresponding photosensors; forming a stack of layers of different thickness and refractive index layers over the photosensors to provide an interferential filter for said photosensors. The stack is obtained by a deposition of a first oxide stack including a first, a second and a third oxide layer over at least one photosensor; moreover, this third oxide layer is obtained by a deposition step of an protecting undoped premetal dielectric layer.

Integrated semiconductor light sensor device and corresponding manufacturing process

The invention relates to a process for manufacturing a light sensor device in a standard CMOS process, including, implanting active areas on a semiconductor substrate to obtain a first integrated region of a corresponding photosensor; and forming a stack of layers having different thickness and refractive index layers over the photosensor to provide interferential filters for the same photosensor. At least one of the above mentioned layers is formed by a transparent metallic oxide having a high refraction index and a corresponding high dielectric constant. In this manner, due to the transparency of the high refraction index material, the design of interferential resonators is rendered more flexible making possible the use of a stack of layers including more than one high refraction index layer.
