Abstract: An ultralong time constant time measurement device includes elementary capacitive elements that are connected in series. Each elementary capacitive element is formed by a stack of a first conductive region, a dielectric layer having a thickness suited for allowing charge to flow by direct tunneling effect, and a second conductive region. The first conductive region is housed in a trench extending from a front face of a semiconductor substrate down into the semiconductor substrate. The dielectric layer rests on the first face of the semiconductor substrate and in particular on a portion of the first conductive region in the trench. The second conductive region rests on the dielectric layer.

Abstract: A method of authenticating a slave device. The method includes initializing, by a host device, a charge retention circuit of the slave device, and receiving, by the host device, an indication of a discharge time of the charge retention circuit. The host device authenticates the slave device based on the received indication of the discharge time of the charge retention device.

Abstract: An EEPROM includes a floating gate transistor having a source region, a channel region and a drain region. A first capa implant zone on a drain-side of the floating gate transistor has a first dopant concentration level. A second capa implant zone in the first capa implant zone adjacent the drain region has a second dopant concentration level that is greater than the first dopant concentration level. A gate oxide region insulates the floating gate electrode from the channel region, first capa implant zone and second capa implant zone. A thickness of the gate oxide region is thinner at the second capa implant zone than at the channel region and first capa implant zone.

Abstract: A system on chip includes an interconnect circuit including at least p input interfaces and at least k output interfaces, p source devices respectively coupled to the p input interfaces and k access ports respectively coupled to the k output interfaces and belonging to a target that includes one or more target devices. Each source device is configured to deliver transactions to the target via one of the access ports. An associated memory of each access port is configured to temporarily store the transactions received by the access port. The target is configured to deliver, for each access port, a fill signal representative of a current fill level of its associated memory. A control circuit is configured to receive the fill signals from the access ports and select the access ports eligible to receive a transaction depending on the current fill levels.

Abstract: A memory device includes a first state transistor and a second state transistor having a common control gate. A first selection transistor is buried in the semiconductor body and coupled to the first state transistor so that current paths of the first selection transistor and first state transistor are coupled in series. A second selection transistor is buried in the semiconductor body and coupled to the second state transistor so that current paths of the second selection transistor and second state transistor are coupled in series. The first and second selection transistors have a common buried selection gate. A dielectric region is located between the common control gate and the semiconductor body. A first bit line is coupled to the first state transistor and a second bit line is coupled to the second state transistor.
